Home

Clearleft is a remote-working company right now. I mean, that’s hardly surprising—just about everyone I know is working from home.

We made this decision on Friday. It was clear that the spread of COVID-19 was going exponential (even with the very incomplete data available in the UK). Despite the wishy-washy advice from the government—which has since pivoted drastically—we made the decision to literally get ahead of the curve. We had one final get-together in the studio yesterday to plan logistics and pick up equipment. Then it was time to start this chapter.

I’ve purloined:

  • one Aeron chair,
  • one big monitor,
  • a wired keyboard,
  • a wireless mouse, and
  • noise-cancelling headphones.

Cassie kindly provided the use of her van to get that stuff home. The Aeron chair proved to be extremely tricky to get through my narrow front door. For a while there, it looked like I’d need to take the door off the hinges but with a whole lotta pushin’ and a-pullin’ Jessica and I managed to somehow get it in.

Now I’ve got a reasonable home studio set up, I can get back to working on that conference talk I’m prepar… Oh.

Yeah, I guess I’ve got a stay of execution on that. For the past few months I’ve had my head down preparing a new hour-long talk for An Event Apart. Yes, it takes me that long to put a talk together—it feels kinda like writing a book. I’d like to think it’s because I’m so meticulous, but the truth is that I’m just very slow at most things. Also, I’m a bad one for procrastinating.

For the past week or so, while I’ve been making pretty darn good progress on the talk, a voice in the back of my head has been whispering “Hey, maybe the conference won’t even happen!” In answer to which, the voice in the front of my head has been saying “Would you shut the fuck up? I’m trying to work here!”

I was due to debut the talk at An Event Apart Seattle in May. Sure enough, that event has quite rightly been cancelled. So have a lot of other excellent events. It’s a real shame, and my heart goes out to event organisers who pour so much of themselves into their events; their love, their care, and not least, their financial risk.

I speak at quite a few events every year. I really, really enjoy it. For one, public speaking is one of the few things I think I’m actually any good at. Also, I just love the chance to meet my peers and collectively nerd out together for a short while.

Then there’s the travel. This year I was planning on drastically reducing my plane travel. I had bagged myself speaking slots in European cities that I could reach by train: Cologne, Strasbourg, even Lisbon, along with domestic destinations like Nottingham, Manchester, and Plymouth. I was quite looking forward to some train adventures. But those will have to wait.

Right now I’m going to settle into this new home routine. It’s not entirely new to me. Back in the early 2000s, I worked from home as a freelancer. Back then, Jessica and I worked not just in the same room, but on opposite ends of the same table!

We’ve got more room now. Jessica has her own office space. I’m getting used to mine. But as Jessica pointed out:

I’ve worked from home for 20(!) years, I love it, I’m made for it, I can’t imagine not doing it—and I’ve gotten absolutely nothing done for the past week.

Newly WFH folks, the situation now is totally unconducive to concentration and productivity. Be gentle with yourselves.

Utopia

Trys and James recently unveiled their Utopia project. They’ve been tinkering away at it behind the scenes for quite a while now.

You can check out the website and read the blog to get the details of how it accomplishes its goal:

Elegantly scale type and space without breakpoints.

I may well be biased, but I really like this project. I’ve been asking myself why I find it so appealing. Here are a few of the attributes of Utopia that strike a chord with me…

It’s collaborative

Collaboration is at the heart of Clearleft’s work. I know everyone says that, but we’ve definitely seen a direct correlation: projects with high levels of collaboration are invariably more successful than projects where people are siloed.

The genesis for Utopia came about after Trys and James worked together on a few different projects. It’s all too easy to let design and development splinter off into their own caves, but on these projects, Trys and James were working (literally) side by side. This meant that they could easily articulate frustrations to one another, and more important, they could easily share their excitement.

The end result of their collaboration is some very clever code. There’s an irony here. This code could be used to discourage collaboration! After all, why would designers and developers sit down together if they can just pass these numbers back and forth?

But I don’t think that Utopia will appeal to designers and developers who work in that way. Born in the spirit of collaboration, I suspect that it will mostly benefit people who value collaboration.

It’s intrinsic

If you’re a control freak, you may not like Utopia. The idea is that you specify the boundaries of what you’re trying to accomplish—minimum/maximum font sizes, minumum/maximum screen sizes, and some modular scales. Then you let the code—and the browser—do all the work.

On the one hand, this feels like surrending control. But on the other hand, because the underlying system is so robust, it’s a way of guaranteeing quality, even in situations you haven’t accounted for.

If someone asks you, “What size will the body copy be when the viewport is 850 pixels wide?”, your answer would have to be “I don’t know …but I do know that it will be appropriate.”

This feels like a very declarative way of designing. It reminds me of the ethos behind Andy and Heydon’s site, Every Layout. They call it algorithmic layout design:

Employing algorithmic layout design means doing away with @media breakpoints, “magic numbers”, and other hacks, to create context-independent layout components. Your future design systems will be more consistent, terser in code, and more malleable in the hands of your users and their devices.

See how breakpoints are mentioned as being a very top-down approach to layout? Remember the tagline for Utopia, which aims for fluid responsive design?

Elegantly scale type and space without breakpoints.

Unsurprisingly, Andy really likes Utopia:

As the co-author of Every Layout, my head nearly fell off from all of the nodding when reading this because this is the exact sort of approach that we preach: setting some rules and letting the browser do the rest.

Heydon describes this mindset as automating intent. I really like that. I think that’s what Utopia does too.

As Heydon said at Patterns Day:

Be your browser’s mentor, not its micromanager.

The idea is that you give it rules, you give it axioms or principles to work on, and you let it do the calculation. You work with the in-built algorithms of the browser and of CSS itself.

This is all possible thanks to improvements to CSS like calc, flexbox and grid. Jen calls this approach intrinsic web design. Last year, I liveblogged her excellent talk at An Event Apart called Designing Intrinsic Layouts.

Utopia feels like it has the same mindset as algorithmic layout design and intrinsic web design. Trys and James are building on the great work already out there, which brings me to the final property of Utopia that appeals to me…

It’s iterative

There isn’t actually much that’s new in Utopia. It’s a combination of existing techniques. I like that. As I said recently:

I’m a great believer in the HTML design principle, Evolution Not Revolution:

It is better to evolve an existing design rather than throwing it away.

First of all, Utopia uses the idea of modular scales in typography. Tim Brown has been championing this idea for years.

Then there’s the idea of typography being fluid and responsive—just like Jason Pamental has been speaking and writing about.

On the code side, Utopia wouldn’t be possible without the work of Mike Reithmuller and his breakthroughs on responsive and fluid typography, which led to Tim’s work on CSS locks.

Utopia takes these building blocks and combines them. So if you’re wondering if it would be a good tool for one of your projects, you can take an equally iterative approach by asking some questions…

Are you using fluid type?

Do your font-sizes increase in proportion to the width of the viewport? I don’t mean in sudden jumps with @media breakpoints—I mean some kind of relationship between font size and the vw (viewport width) unit. If so, you’re probably using some kind of mechanism to cap the minimum and maximum font sizes—CSS locks.

I’m using that technique on Resilient Web Design. But I’m not changing the relative difference between different sized elements—body copy, headings, etc.—as the screen size changes.

Are you using modular scales?

Does your type system have some kind of ratio that describes the increase in type sizes? You probably have more than one ratio (unlike Resilient Web Design). The ratio for small screens should probably be smaller than the ratio for big screens. But rather than jump from one ratio to another at an arbitrary breakpoint, Utopia allows the ratio to be fluid.

So it’s not just that font sizes are increasing as the screen gets larger; the comparative difference is also subtly changing. That means there’s never a sudden jump in font size at any time.

Are you using custom properties?

A technical detail this, but the magic of Utopia relies on two powerful CSS features: calc() and custom properties. These two workhorses are used by Utopia to generate some CSS that you can stick at the start of your stylesheet. If you ever need to make changes, all the parameters are defined at the top of the code block. Tweak those numbers and watch everything cascade.

You’ll see that there’s one—and only one—media query in there. This is quite clever. Usually with CSS locks, you’d need to have a media query for every different font size in order to cap its growth at the maximum screen size. With Utopia, the maximum screen size—100vw—is abstracted into a variable (a custom property). The media query then changes its value to be the upper end of your CSS lock. So it doesn’t matter how many different font sizes you’re setting: because they all use that custom property, one single media query takes care of capping the growth of every font size declaration.

If you’re already using CSS locks, modular scales, and custom properties, Utopia is almost certainly going to be a good fit for you.

If you’re not yet using those techniques, but you’d like to, I highly recommend using Utopia on your next project.

Patterns Day video and audio

If you missed out on Patterns Day this year, you can still get a pale imitation of the experience of being there by watching videos of the talks.

Here are the videos, and if you’re not that into visuals, here’s a podcast of the talks (you can subscribe to this RSS feed in your podcasting app of choice).

On Twitter, Chris mentioned that “It would be nice if the talks had their topic listed,” which is a fair point. So here goes:

It’s fascinating to see emergent themes (other than, y’know, the obvious theme of design systems) in different talks. In comparison to the first Patterns Day, it felt like there was a healthy degree of questioning and scepticism—there were plenty of reminders that design systems aren’t a silver bullet. And I very much appreciated Yaili’s point that when you see beautifully polished design systems that have been made public, it’s like seeing the edited Instagram version of someone’s life. That reminded me of Responsive Day Out when Sarah Parmenter, the first speaker at the very first event, opened everything by saying “most of us are winging it.”

I can see the value in coming to a conference to hear stories from people who solved hard problems, but I think there’s equal value in coming to a conference to hear stories from people who are still grappling with hard problems. It’s reassuring. I definitely got the vibe from people at Patterns Day that it was a real relief to hear that nobody’s got this figured out.

There was also a great appreciation for the “big picture” perspective on offer at Patterns Day. For myself, I know that I’ll be cogitating upon Danielle’s talk and Emil’s talk for some time to come—both are packed full of ineresting ideas.

Good thing we’ve got the videos and the podcast to revisit whenever we want.

And if you’re itching for another event dedicated to design systems, I highly recommend snagging a ticket for the Clarity conference in San Francisco next month.

Movie Knight

I mentioned how much I enjoyed Mike Hill’s talk at Beyond Tellerrand in Düsseldorf:

Mike gave a talk called The Power of Metaphor and it’s absolutely brilliant. It covers the monomyth (the hero’s journey) and Jungian archetypes, illustrated with the examples Star Wars, The Dark Knight, and Jurassic Park.

At Clearleft, I’m planning to reprise the workshop I did a few years ago about narrative structure—very handy for anyone preparing a conference talk, blog post, case study, or anything really:

Ellen and I have been enjoying some great philosophical discussions about exactly what a story is, and how does it differ from a narrative structure, or a plot. I really love Ellen’s working definition: Narrative. In Space. Over Time.

This led me to think that there’s a lot that we can borrow from the world of storytelling—films, novels, fairy tales—not necessarily about the stories themselves, but the kind of narrative structures we could use to tell those stories. After all, the story itself is often the same one that’s been told time and time again—The Hero’s Journey, or some variation thereof.

I realised that Mike’s monomyth talk aligns nicely with my workshop. So I decided to prep my fellow Clearlefties for the workshop with a movie night.

Popcorn was popped, pizza was ordered, and comfy chairs were suitably arranged. Then we watched Mike’s talk. Everyone loved it. Then it was decision time. Which of three films covered in the talk would we watch? We put it to a vote.

It came out as an equal tie between Jurassic Park and The Dark Knight. How would we resolve this? A coin toss!

The toss went to The Dark Knight. In retrospect, a coin toss was a supremely fitting way to decide to watch that film.

It was fun to watch it again, particularly through the lens of Mike’s analyis of its Jungian archetypes.

But I still think the film is about game theory.

Patterns Day Two

Who says the sequels can’t be even better than the original? The second Patterns Day was The Empire Strikes Back, The Godfather Part II, and The Wrath of Khan all rolled into one …but, y’know, with design systems.

If you were there, then you know how good it was. If you weren’t, sorry. Audio of the talks should be available soon though, with video following on.

The talks were superb! I know I’m biased becuase I put the line-up together, but even so, I was blown away by the quality of the talks. There were some big-picture questioning talks, a sequence of nitty-gritty code talks in the middle, and galaxy-brain philosophical thoughts at the end. A perfect mix, in my opinion.

Words cannot express how grateful I am to Alla, Yaili, Amy, Danielle, Heydon, Varya, Una, and Emil. They really gave it their all! Some of them are seasoned speakers, and some of them are new to speaking on stage, but all of them delivered the goods above and beyond what I expected.

Big thanks to my Clearleft compadres for making everything run smoothly: Jason, Amy, Cassie, Chris, Trys, Hana, and especially Sophia for doing all the hard work behind the scenes. Trys took some remarkable photos too. He posted some on Twitter, and some on his site, but there are more to come.

Me on stage. Inside the Duke of York's for Patterns Day 2

And if you came to Patterns Day 2, thank you very, very much. I really appreciate you being there. I hope you enjoyed it even half as much as I did, because I had a ball!

Once again, thanks to buildit @ wipro digital for sponsoring the pastries and coffee, as well as running a fun giveaway on the day. Many thank to Bulb for sponsoring the forthcoming videos. Thanks again to Drew for recording the audio. And big thanks to Brighton’s own Holler Brewery for very kindly offering every attendee a free drink—the weather (and the beer) was perfect for post-conference discussion!

It was incredibly heartwarming to hear how much people enjoyed the event. I was especially pleased that people were enjoying one another’s company as much as the conference itself. I knew that quite a few people were coming in groups from work, while other people were coming by themselves. I hoped there’d be lots of interaction between attendees, and I’m so, so glad there was!

You’ve all made me very happy.

The schedule for Patterns Day

Patterns Day is less than three weeks away—exciting!

We’re going to start the day at a nice civilised time. Registration is from 9am. There will be tea, coffee, and pastries, so get there in plenty of time to register and have a nice chat with your fellow attendees. There’ll be breaks throughout the day too.

Those yummy pastries and hot drinks are supplied courtesy of our sponsors Buildit @ Wipro Digital—many thanks to them!

Each talk will be 30 minutes long. There’ll be two talks back-to-back and then a break. That gives you plenty of breathing space to absorb all those knowledge bombs that the speakers will be dropping.

Lunch will be a good hour and a half. Lunch isn’t provided so you can explore the neighbourhood where there are plenty of treats on offer. And your Patterns Day badge will even get you some discounts…

The lovely Café Rust is offering these deals to attendees:

  • Cake and coffee for £5
  • Cake and cup of tea for £4
  • Sandwich and a drink for £7

The Joker (right across the street from the conference venue) is offering a 10% discount of food and drinks (but not cocktails) to Patterns Day attendees. I highly recommend their hot wings. Try the Rufio sauce—it’s awesome! Do not try the Shadow—it will kill you.

Here’s how the day is looking:

Closing remarks

We should be out of the Duke of York’s by 4:45pm after a fantastic day of talks. At that point, we can head around the corner (literally) to Holler Brewery. They are very kindly offering each attendee a free drink! Over to them:

Holler is a community based brewery, always at the centre of the local community. Here to make great beer, but also to help support community run pubs, carnival societies, mental health charities, children’s amateur dramatic groups, local arts groups and loads more, because these are what keep our communities healthy and together… the people in them!

Holler loves great beer and its way of bringing people together. They are excited to be welcoming the Patterns Day attendees and the design community to the taproom.

Terms and conditions:

  • One token entitles to you one Holler beer or one soft drink
  • Redeemable only on Friday 28th June 2019 between 4:45 and 20:00
  • You must hand your token over to the bar team

You’ll get your token when you register in the morning, along with your sticker. That’s right; sticker. Every expense has been spared so you won’t even have a name badge on a lanyard, just a nice discrete but recognisable sticker for the event.

I am so, so excited for Patterns Day! See you at the Duke of York’s on June 28th!

Sponsor Patterns Day

Patterns Day 2 is sold out! Yay!

I didn’t even get the chance to announce the full line-up before all the tickets were sold. That was meant to my marketing strategy, see? I’d announce some more speakers every few weeks, and that would encourage more people to buy tickets. Turns out that I didn’t need to do that.

But I’m still going to announce the final two speakers here becuase I’m so excited about them—Danielle Huntrods and Varya Stepanova!

Danielle is absolutely brilliant. I know this from personal experience because I worked alongside her at Clearleft for three years. Now she’s at Bulb and I can’t wait for everyone at Patterns Day to hear her galaxy brain thoughts on design systems.

And how could I not have Varya at Patterns Day? She lives and breathes design systems. Whether it’s coding, writing, speaking, or training, she’s got years of experience to share. Ever used BEM? Yeah, that was Varya.

Anyway, if you’ve got your ticket for Patterns Day, you’re in for a treat.

If you didn’t manage to get a ticket for Patterns Day …sorry.

But do not despair. There is still one possible way of securing an elusive Patterns Day ticket: get your company to sponsor the event.

We’ve already got one sponsor—buildit @ wipro digital—who are kindly covering the costs for teas, coffees, and pastries. Now I’m looking for another sponsor to cover the costs of making video recordings of the talks.

The cost of sponsorship is £2000. In exchange, I can’t offer you a sponsor stand or anything like that—there’s just no room at the venue. But you will earn my undying thanks, and you’ll get your logo on the website and on the screen in between talks on the day (and on the final videos).

I can also give you four tickets to Patterns Day.

This is a sponsorship strategy that I like to call “blackmail.”

If you were really hoping to bring your team to Patterns Day, but you left it too late to get your tickets, now’s your chance. Convince your company to sponsor the event (and let’s face it, £2000 is a rounding error on some company’s books). Then you and your colleagues need not live with eternal regret and FOMO.

Drop me a line. Let’s talk.

Head’s role

I have a bittersweet feeling today. Danielle is moving on from Clearleft.

I used to get really down when people left. Over time I’ve learned not to take it as such a bad thing. I mean, of course it’s sad when someone moves on, but for them, it’s exciting. And I should be sharing in that excitement, not putting a damper on it.

Besides, people tend to stay at Clearleft for years and years—in the tech world, that’s unheard of. So it’s not really so terrible when they decide to head out to pastures new. They’ll always be Clearlefties. Just look at the lovely parting words from Harry, Paul, Ellen, and Ben:

Working at Clearleft was one of the best decisions I ever made. 6 years of some work that I’m most proud of, amongst some of the finest thinkers I’ve ever met.

(Side note: I’ve been thinking about starting a podcast where I chat to ex-Clearlefties. We could reflect on the past, look to the future, and generally just have a catch-up. Would that be self indulgent or interesting? Let me know what you think.)

So of course I’m going to miss working with Danielle, but as with other former ‘lefties, I’m genuinely excited to see what happens next for her. Clearleft has had an excellent three years of her time and now it’s another company’s turn.

In the spirit of “one door closes, another opens,” Danielle’s departure creates an opportunity for someone else. Fancy working at Clearleft? Well, we’re looking for a head of front-end development.

Do you remember back at the start of the year when we were hiring a front-end developer, and I wrote about writing job postings?

My first instinct was to look at other job ads and take my cue from them. But, let’s face it, most job ads are badly written, and prone to turning into laundry lists. So I decided to just write like I normally would. You know, like a human.

That worked out really well. We ended up hiring the ridiculously talented Trys Mudford. Success!

So I’ve taken the same approach with this job ad. I’ve tried to paint as clear and honest a picture as I can of what this role would entail. Like it says, there are three main parts to the job:

  • business support,
  • technical leadership, and
  • professional development.

Now, I could easily imagine someone reading the job description and thinking, “Nope! Not for me.” Let’s face it: There Will Be Meetings. And a whole lotta context switching:

Within the course of one day, you might go from thinking about thorny code problems to helping someone on your team with their career plans to figuring out how to land new business in a previously uncharted area of technology.

I can equally imagine someone reading that and thinking “Yes! This is what I’ve been waiting for.”

Oh, and in case you’re wondering why I’m not taking this role …well, in the short term, I will for a while, but I’d consider myself qualified for maybe one third to one half of the required tasks. Yes, I can handle the professional development side of things (in fact, I really, really enjoy that). I can handle some of the technical leadership stuff—if we’re talking about HTML, CSS, JavaScript, accessibility, and performance. But all of the back-of-the-front-end stuff—build tools, libraries, toolchains—is beyond me. And I think I’d be rubbish at the business support stuff, mostly because that doesn’t excite me much. But maybe it excites you! If so, you should apply.

I can picture a few scenarios where this role could be the ideal career move…

Suppose you’re a lead developer at a product company. You enjoy leading a team of devs, and you like setting the technical direction when it comes to the tools and techniques being used. But maybe you’re frustrated by always working on the same product with the same tech stack. The agency world, where every project is different, might be exactly what you’re looking for.

Or maybe you’re an accomplished and experienced front-end developer, freelancing and contracting for years. Perhaps you’re less enamoured with being so hands-on with the code all the time. Maybe you’ve realised that what you really enjoy is solving problems and evaluating techologies, and you’d be absolutely fine with having someone else take care of the implementation. Moving into a lead role like this might be the perfect way to make the best use of your time and have more impact with your decisions.

You get the idea. If any of this is sounding intriguing to you, you should definitely apply for the role. What do you have to lose?

Also, as it says in the job ad:

If you’re from a group that is under-represented in tech, please don’t hesitate to get in touch.

Three more Patterns Day speakers

There are 73 days to go until Patterns Day. Do you have your ticket yet?

Perhaps you’ve been holding out for some more information on the line-up. Well, I’m more than happy to share the latest news with you—today there are three new speakers on the bill…

Emil Björklund, the technical director at the Malmö outpost of Swedish agency inUse, is a super-smart person I’ve known for many years. Last year, I saw him on stage in his home town at the Confront conference sharing some of his ideas on design systems. He blew my mind! I told him there and then that he had to come to Brighton and expand on those thoughts some more. This is going to be an unmissable big-picture talk in the style of Paul’s superb talk last year.

Speaking of superb talks from last year, Alla Kholmatova is back! Her closing talk from the first Patterns Day was so fantastic that it I just had to have her come back. Oh, and since then, her brilliant book on Design Systems came out. She’s going to have a lot to share!

The one thing that I felt was missing from the first Patterns Day was a focus on inclusive design. I’m remedying that this time. Heydon Pickering, creator of the Inclusive Components website—and the accompanying book—is speaking at Patterns Day. I’m very excited about this. Given that Heydon has a habit of casually dropping knowledge bombs like the lobotomised owl selector and the flexbox holy albatross, I can’t wait to see what he unleashes on stage in Brighton on June 28th.

Emil Björklund Alla Kholmatova Heydon Pickering
Emil, Alla, and Heydon

Be there or be square.

Tickets for Patterns Day are still available, but you probably don’t want to leave it ‘till the last minute to get yours. Just sayin’.

The current—still incomplete—line-up comprises:

That isn’t even the full roster of speakers, and it’s already an unmissable event!

I very much hope you’ll join me in the beautiful Duke of York’s cinema on June 28th for a great day of design system nerdery.

Patterns Day 2: June 28th, 2019

Surprise! Patterns Day is back!

The first Patterns Day was in the Summer of 2017, and it was a glorious—a single day devoted to all things design system-y: pattern libraries, style guides, maintainability, reusability. It was a lot of fun, so let’s do it again!

Patterns Day 2 will take place on Friday, June 28th, in the beautiful Duke of York’s cinema in Brighton. If you went to the first Patterns Day, then you’ll know how luxuriously comfy it is in there.

Tickets are £175+VAT. The format will likely be the same as before: an action-packed day of eight talks, each 30 minutes long.

I’ve got an amazing line-up of speakers, but instead of telling you the whole line-up straightaway, I’m going to tease a little bit, and announce more speakers over the next few weeks and months. For now, here are the first three speakers, to give you an idea of the quality you can expect:

  • All the way from the US of A, it’s Una Kravets, who needs no introduction.
  • From the Government Digital Service, we’ve got Amy Hupe—she’ll have plenty to share about the GOV.UK design system.
  • And we’ve got Yaili, now a senior designer at Microsoft, where she works on the Azure DevOps design system.

Patterns Day will have something for everyone. We’ll be covering design, development, content strategy, product management, and accessibility. So you might want to make this a one-day outing for your whole team.

If you want to get a feel for what the day will be like, you can watch the videos of last year’s talks

Tickets for last year’s Patterns Day went fairly fast—the Duke of York’s doesn’t have a huge capacity—so don’t dilly-dally too long before grabbing your ticket!

Writing for hiring

Cassie joined Clearleft as a junior front-end developer last year. It’s really wonderful having her around. It’s a win-win situation: she’s enthusiastic and eager to learn; I’m keen to help her skill up in any way I can. And it’s working out great for the company—she has already demonstrated that she can produce quality HTML and CSS.

I’m very happy about Cassie’s success, not just on a personal level, but also from a business perspective. Hiring people into junior roles—when you’ve got the time and ability to train them—is an excellent policy. Hiring Charlotte back in 2014 was Clearleft’s first foray into hiring for a junior front-end dev position and it was a huge success. Cassie is demonstrating that it wasn’t just a fluke.

Alas, we can’t only hire junior developers. We’ve got a lot of work in the pipeline right now and we’re going to need a full-time seasoned developer who can hit the ground running. That’s why Clearleft is recruiting for a senior front-end developer.

As lead developer, Danielle will make the hiring decision, but because she’s so busy on project work right now—hence the need to hire more people—I’m trying to help her out any way I can. I offered to write the job description.

Seeing as I couldn’t just write “A clone of Danielle, please”, I had to think about what makes for a great front-end developer who uses their experience wisely. But I didn’t want to create a list of requirements, and I certainly didn’t want to create a list of specific technologies.

My first instinct was to look at other job ads and take my cue from them. But, let’s face it, most job ads are badly written, and prone to turning into laundry lists. So I decided to just write like I normally would. You know, like a human.

Here’s what I wrote. I hope it’s okay. I don’t really have much to compare it to, other than what I don’t want it to be.

Have a read of it and see what you think. And if you’re an experienced front-end developer who’d like to work by the seaside, you should apply for the role.

Prototypes and production

When we do front-end development at Clearleft, we’re usually delivering production code, often in the form of a component library. That means our priorities are performance, accessibility, robustness, and other markers of quality when it comes to web development.

But every so often, we use the materials of front-end development—HTML, CSS, and JavaScript—to produce something that isn’t intended for production. I’m talking about prototyping.

There are plenty of non-code prototyping tools out there, and our designers often reach for them to communicate subtleties like motion design. But when it comes to testing a prototype with real users, it’s hard to beat the flexibility of HTML, CSS, and JavaScript. Load it up in a browser and away you go.

We do a lot of design sprints, where time is of the essence. The prototype we produce on the penultimate day of the sprint definitely won’t be production quality, but it will be good enough to test.

What’s interesting is that—when it comes to prototyping—our usual front-end priorities can and should go out the window. The priority now is speed. If that means sacrificing semantics or performance, then so be it. If I’m building a prototype and I find myself thinking “now, what’s the right class name for this component?”, then I know I’m in the wrong mindset. That question might be valid for production code, but it’s a waste of time for prototypes.

So these two kinds of work require very different attitudes. For production work, quality is key. For prototyping, making something quickly is what matters.

Whereas I would think long and hard about the performance impacts of third-party libraries and frameworks on a public project, I won’t give it a second thought when it comes to a prototype. Throw all the JavaScript frameworks and CSS libraries you want at it (although I would argue that in-browser technologies like CSS Grid have made CSS libraries like Bootstrap less necessary, even for prototyping).

Alternating between production projects and prototyping projects can be quite fun, if a little disorienting. It’s almost like I have to flip a switch in my brain to change tracks.

When a prototype is successful, works great, and tests well, there’s a real temptation to use the prototype code as the basis for the final product. Don’t do this! I’ve made that mistake in the past and it always ends badly. I ended up spending far more time trying to wrangle prototype code to a production level than if I had just started from a clean slate.

Build prototypes to test ideas, designs, interactions, and interfaces …and then throw the code away. The value of a prototype is in answering questions and testing hypotheses. Don’t fall for the sunk cost fallacy when it’s time to switch over into production mode.

Of course it should go without saying that you should never, ever release prototype code into production.

And yet…

More and more live sites seem to be built with a prototyping mindset. Weighty JavaScript frameworks are used regardless of appropriateness. Accessibility, if it’s even considered at all, is relegated to an afterthought. Fragile architectures are employed that rely on first loading and then executing JavaScript in order to render basic content. Developer experience is prioritised over user experience.

Heydon recently highlighted an article that offered this tip for aspiring web developers:

As for HTML, there’s not much to learn right away and you can kind of learn as you go, but before making your first templates, know the difference between in-line elements like span and how they differ from block ones like div.

That’s perfectly reasonable advice …if you’re building a prototype. But if you’re building something for public consumption, you have a duty of care to the end users.

A framework for web performance

Here at Clearleft, we’ve recently been doing some front-end consultancy. That prompted me to jot down thoughts on design principles and performance:

We continued with some more performance work this week. Having already covered some of the nitty-gritty performance tactics like font-loading, image optimisation, etc., we wanted to take a step back and formulate an ongoing strategy for performance.

When it comes to web performance, the eternal question is “What should we measure?” The answer to that question will determine where you then concentrate your efforts—whatever it is your measuring, that’s what you’ll be looking to improve.

I started by drawing a distinction between measurements of quantities and measurements of time. Quantities are quite easy to measure. You can measure these quantities using nothing more than browser dev tools:

  • overall file size (page weight + assets), and
  • number of requests.

I think it’s good to measure these quantities, and I think it’s good to have a performance budget for them. But I also think they’re table stakes. They don’t actually tell you much about the impact that performance is having on the user experience. For that, we need to enumerate moments in time:

  • time to first byte,
  • time to first render,
  • time to first meaningful paint, and
  • time to first meaningful interaction.

There’s one more moment in time, which is the time until DOM content is loaded. But I’m not sure that has a direct effect on how performance is perceived, so it feels like it belongs more in the category of quantities than time.

Next, we listed out all the factors that could affect each of the moments in time. For example, the time to first byte depends on the speed of the network that the user is on. It also depends on how speedily your server (or Content Delivery Network) can return a response. Meanwhile, time to first render is affected by the speed of the user’s network, but it’s also affected by how many blocking elements are on the critical path.

By listing all the factors out, we can draw a distinction between the factors that are outside of our control, and the factors that we can do something about. So while we might not be able to do anything about the speed of the user’s network, we might well be able to optimise the speed at which our server returns a response, or we might be able to defer some assets that are currently blocking the critical path.

Factors
1st byte
  • server speed
  • network speed
1st render
  • network speed
  • critical path assets
1st meaningful paint
  • network speed
  • font-loading strategy
  • image optimisation
1st meaningful interaction
  • network speed
  • device processing power
  • JavaScript size

So far, everything in our list of performance-affecting factors is related to the first visit. It’s worth drawing up a second list to document all the factors for subsequent visits. This will look the same as the list for first visits, but with the crucial difference that caching now becomes a factor.

First visit factors Repeat visit factors
1st byte
  • server speed
  • network speed
  • server speed
  • network speed
  • caching
1st render
  • network speed
  • critical path assets
  • network speed
  • critical path assets
  • caching
1st meaningful paint
  • network speed
  • font-loading strategy
  • image optimisation
  • network speed
  • font-loading strategy
  • image optimisation
  • caching
1st meaningful interaction
  • network speed
  • device processing power
  • JavaScript size
  • network speed
  • device processing power
  • JavaScript size
  • caching

Alright. Now it’s time to get some numbers for each of the four moments in time. I use Web Page Test for this. Choose a realistic setting, like 3G on an Android from the East coast of the USA. Under advanced settings, be sure to select “First View and Repeat View” so that you can put those numbers in two different columns.

Here are some numbers for adactio.com:

First visit time Repeat visit time
1st byte 1.476 seconds 1.215 seconds
1st render 2.633 seconds 1.930 seconds
1st meaningful paint 2.633 seconds 1.930 seconds
1st meaningful interaction 2.868 seconds 2.083 seconds

I’m getting the same numbers for first render as first meaningful paint. That tells me that there’s no point in trying to optimise my font-loading, for example …which makes total sense, because adactio.com isn’t using any web fonts. But on a different site, you might see a big gap between those numbers.

I am seeing a gap between time to first byte and time to first render. That tells me that I might be able to get some blocking requests off the critical path. Sure enough, I’m currently referencing an external stylesheet in the head of adactio.com—if I were to inline critical styles and defer the loading of that stylesheet, I should be able to narrow that gap.

A straightforward site like adactio.com isn’t going to have much to worry about when it comes to the time to first meaningful interaction, but on other sites, this can be a significant bottleneck. If you’re sending UI elements in the initial HTML, but then waiting for JavaScript to “hydrate” those elements into working, the user can end up in an uncanny valley of tapping on page elements that look fine, but aren’t ready yet.

My point is, you’re going to see very different distributions of numbers depending on the kind of site you’re testing. There’s no one-size-fits-all metric to focus on.

Now that you’ve got numbers for how your site is currently performing, you can create two new columns: one of those is a list of first-visit targets, the other is a list of repeat-visit targets for each moment in time. Try to keep them realistic.

For example, if I could reduce the time to first render on adactio.com by 0.5 seconds, my goals would look like this:

First visit goal Repeat visit goal
1st byte 1.476 seconds 1.215 seconds
1st render 2.133 seconds 1.430 seconds
1st meaningful paint 2.133 seconds 1.430 seconds
1st meaningful interaction 2.368 seconds 1.583 seconds

See how the 0.5 seconds saving cascades down into the other numbers?

Alright! Now I’ve got something to aim for. It might also be worth having an extra column to record which of the moments in time are high priority, which are medium priority, and which are low priority.

Priority
1st byte Medium
1st render High
1st meaningful paint Low
1st meaningful interaction Low

Your goals and priorities may be quite different.

I think this is a fairly useful framework for figuring out where to focus when it comes to web performance. If you’d like to give it a go, I’ve made a web performance chart for you to print out and fill in. Here’s a PDF version if that’s easier for printing. Or you can download the HTML version if you want to edit it.

I have to say, I’m really enjoying the front-end consultancy work we’ve been doing at Clearleft around performance and related technologies, like offline functionality. I’d like to do more of it. If you’d like some help in prioritising performance at your company, please get in touch. Let’s make the web faster together.

The history of design systems at Clearleft

Danielle has posted a brief update on Fractal:

We decided to ask the Fractal community for help, and the response has been overwhelming. We’ve received so many offers of support in all forms that we can safely say that development will be starting up again shortly.

It’s so gratifying to see that other people are finding Fractal to be as useful to them as it is to us. We very much appreciate all their support!

Although Fractal itself is barely two years old, it’s part of a much longer legacy at Clearleft

It all started with Natalie. She gave a presentation back in 2009 called Practical Maintainable CSS . She talks about something called a pattern porfolio—a deliverable that expresses every component and documents how the markup and CSS should be used.

When Anna was interning at Clearleft, she was paired up with Natalie so she was being exposed to these ideas. She then expanded on them, talking about Front-end Style Guides. She literally wrote the book on the topic, and starting curating the fantastic collection of examples at styleguides.io.

When Paul joined Clearleft, it was a perfect fit. He was already obsessed with style guides (like the BBC’s Global Experience Language) and started writing and talking about styleguides for the web:

At Clearleft, rather than deliver an inflexible set of static pages, we present our code as a series of modular components (a ‘pattern portfolio’) that can be assembled into different configurations and page layouts as required.

Such systematic thinking was instigated by Natalie, yet this is something we continually iterate upon.

To see the evolution of Paul’s thinking, you can read his three part series from last year on designing systems:

  1. Theory, Practice, and the Unfortunate In-between,
  2. Layers of Longevity, and
  3. Components and Composition

Later, Charlotte joined Clearleft as a junior developer, and up until that point, hadn’t been exposed to the idea of pattern libraries or design systems. But it soon became clear that she had found her calling. She wrote a brilliant article for A List Apart called From Pages to Patterns: An Exercise for Everyone and she started speaking about design systems at conferences like Beyond Tellerrand. Here, she acknowledges the changing terminology over the years:

Pattern portfolio is a term used by Natalie Downe when she started using the technique at Clearleft back in 2009.

Front-end style guides is another term I’ve heard a lot.

Personally, I don’t think it matters what you call your system as long as it’s appropriate to the project and everyone uses it. Today I’m going to use the term “pattern library”.

(Mark was always a fan of the term “component library”.)

Now Charlotte is a product manager at Ansarada in Sydney and the product she manages is …the design system!

Thinking back to my work on starting design systems, I didn’t realise straight away that I was working on a product. Yet, the questions we ask are similar to those we ask of any product when we start out. We make decisions on things like: design, architecture, tooling, user experience, code, releases, consumption, communication, and more.

It’s been fascinating to watch the evolution of design systems at Clearleft, accompanied by an evolution in language: pattern portfolios; front-end style guides; pattern libraries; design systems.

There’s been a corresponding evolution in prioritisation. Where Natalie was using pattern portfolios as a deliverable for handover, Danielle is now involved in the integration of design systems within a client’s team. The focus on efficiency and consistency that Natalie began is now expressed in terms of design ops—creating living systems that everyone is involved in.

When I step back and look at the history of design systems on the web, there are some obvious names that have really driven their evolution and adoption, like Jina Anne, Brad Frost, and Alla Kholmatova. But I’m amazed at the amount of people who have been through Clearleft’s doors that have contributed so, so much to this field:

Natalie Downe, Anna Debenham, Paul Lloyd, Mark Perkins, Charlotte Jackson, and Danielle Huntrods …thank you all!

Altering expectations

Luke has written up the selection process he went through when Clearleft was designing the Virgin Holidays app. When it comes to deploying on mobile, there were three options:

  1. Native apps
  2. A progressive web app
  3. A hybrid app

The Virgin Holidays team went with that third option.

Now, it will come as no surprise that I’m a big fan of the second option: building a progressive web app (or turning an existing site into a progressive web app). I think a progressive web app is a great solution for travel apps, and the use-case that Luke describes sounds perfect:

Easy access to resort staff and holiday details that could be viewed offline to help as many customers as possible travel without stress and enjoy a fantastic holiday

Luke explains why they choice not to go with a progressive web app.

The current level of support and leap in understanding meant we’d risk alienating many of our customers.

The issue of support is one that is largely fixed at this point. When Clearleft was working on the Virgin Holidays app, service workers hadn’t landed in iOS. Hence, the risk of alienating a lot of customers. But now that Mobile Safari has offline capabilities, that’s no longer a problem.

But it’s the second reason that’s trickier:

Simply put, customers already expected to find us in the App Store and are familiar with what apps can historically offer over websites.

I think this is the biggest challenge facing progressive web apps: battling expectations.

For over a decade, people have formed ideas about what to expect from the web and what to expect from native. From a technical perspective, native and web have become closer and closer in capabilities. But people’s expectations move slower than technological changes.

First of all, there’s the whole issue of discovery: will people understand that they can “install” a website and expect it to behave exactly like a native app? This is where install prompts and ambient badging come in. I think ambient badging is the way to go, but it’s still a tricky concept to explain to people.

But there’s another way of looking at the current situation. Instead of seeing people’s expectations as a negative factor, maybe it’s an opportunity. There’s an opportunity right now for companies to be as groundbreaking and trendsetting as Wired.com when it switched to CSS for layout, or The Boston Globe when it launched its responsive site.

It makes for a great story. Just look at the Pinterest progressive web app for an example (skip to the end to get to the numbers):

Weekly active users on mobile web have increased 103 percent year-over-year overall, with a 156 percent increase in Brazil and 312 percent increase in India. On the engagement side, session length increased by 296 percent, the number of Pins seen increased by 401 percent and people were 295 percent more likely to save a Pin to a board. Those are amazing in and of themselves, but the growth front is where things really shined. Logins increased by 370 percent and new signups increased by 843 percent year-over-year. Since we shipped the new experience, mobile web has become the top platform for new signups. And for fun, in less than 6 months since fully shipping, we already have 800 thousand weekly users using our PWA like a native app (from their homescreen).

Now admittedly their previous mobile web experience was a dreadful doorslam, but still, those are some amazing statistics!

Maybe we’re underestimating the malleability of people’s expectations when it comes to the web on mobile. Perhaps the inertia we think we’re battling against isn’t such a problem as long as we give people a fast, reliable, engaging experience.

If you build that, they will come.

Clearleft.com is a progressive web app

What’s that old saying? The cobbler’s children have no shoes that work offline. Or something.

It’s been over a year since the Clearleft site relaunched and I listed some of the next steps I had planned:

Service worker. It’s a no-brainer. Now that the Clearleft site is (finally!) running on HTTPS, having a simple service worker to cache static assets like CSS, JavaScript and some images seems like the obvious next step.

You know how it is. Those no-brainer tasks are exactly the kind of thing that end up on a to-do list without ever quite getting to-done. Meanwhile I’ve been writing and speaking about how any website can be a progressive web app. I think Alanis Morissette used to sing about this sort of situation.

Enough is enough! Clearleft.com is now a progressive web app. It has a manifest file and a service worker script.

The service worker logic is fairly straightforward, and taken almost verbatim from Going Offline. As you navigate around the site, the service worker applies different logic depending on the kind of file you’re requesting:

  • Pages are served fresh from the network, falling back to the cache when there’s a problem.
  • Everything else is served from the cache where possible, resorting to the network only if there’s no match in the cache—quite the performance boost!

In both cases, if a page or a file is retrieved from the network, it’s gets put into a cache. I’ve got one cache for pages, and another for everything else. And even if a file is retrieved from that cache, I still fire off a fetch request to grab a fresh copy for the cache. So while there’s a chance that a stale file might be served up, it will only ever be slightly stale, and the next time it’s requested, it’ll be fresh.

In the worst-case scenario, when a page can’t be retrieved from the network or the cache, you end up seeing a custom offline page. There you can see a list of any pages that are cached (meaning you can revisit them even without an internet connection).

A custom offline page showing a list of URLs.

It’s not ideal—page titles would be friendlier than URLs—but it’s a start. I’m sure I’ll revisit it soon. Honest.

Oh, and after a year of procrastinating about doing this, guess how long it took? About half a day. Admittedly, this isn’t my first progressive web app, and the more you build ‘em, the easier it gets. Still, it’s a classic example of a small investment of time leading to a big improvement in performance and user experience.

If you think your company’s website could benefit from being a progressive web app (and believe me, it definitely could), you have a couple of options:

  1. Arm yourself with a copy of Going Offline and give it a go yourself. Or
  2. Get in touch with Clearleft. We can help you. (See, I can say that with a straight face now that we’re practicing what we preach.)

Either way, don’t dilly dally …like I did.

That new-book smell

The first copies of Going Offline showed up today! This is my own personal stash, sent just a few days before the official shipping date of next Monday.

I am excite!

To say I was excited when I opened the box of books would be an understatement. I was positively squealing with joy!

Others in the Clearleft office shared in my excitement. Everyone did that inevitable thing, where you take a fresh-out-of-the-box book, open it up and press it against your nose. It’s like the bookworm equivalent of sniffing glue.

Actually, it basically is sniffing glue. I mean, that’s what’s in the book binding. But let’s pretend that we’re breathing in the intoxicating aroma of freshly-minted words.

If you’d like to bury your nose in a collection of my words glued together in a beautifully-designed package, you can pre-order the book now and await delivery of the paperback next week.

Global Diversity CFP Day—Brighton edition

There are enough middle-aged straight white men like me speaking at conferences. That’s why the Global Diversity Call-For-Proposals Day is happening this Saturday, February 3rd.

The purpose is two-fold. One is to encourage a diverse range of people to submit talk proposals to conferences. The other is to help with the specifics—coming with ideas, writing a good title and abstract, preparing the presentation, and all that.

Julie is organising the Brighton edition. Clearleft are providing the venue—68 Middle Street. I’ll be on hand to facilitate. Rosa and Dot will be doing the real work, mentoring the attendees.

If you’ve ever thought about submitting a talk proposal to a conference but just don’t know where to start, or if you’re just interested in the idea, please do come along on Saturday. It’s starts at 11am and will be all wrapped up by 3pm.

See you there!

Design ops for design systems

Leading Design was one of the best events I attended last year. To be honest, that surprised me—I wasn’t sure how relevant it would be to me, but it turned out to be the most on-the-nose conference I could’ve wished for.

Seeing as the event was all about design leadership, there was inevitably some talk of design ops. But I noticed that the term was being used in two different ways.

Sometimes a speaker would talk about design ops and mean “operations, specifically for designers.” That means all the usual office practicalities—equipment, furniture, software—that designers might need to do their jobs. For example, one of the speakers recommended having a dedicated design ops person rather than trying to juggle that yourself. That’s good advice, as long as you understand what’s meant by design ops in that context.

There’s another context of use for the phrase “design ops”, and it’s one that we use far more often at Clearleft. It’s related to design systems.

Now, “design system” is itself a term that can be ambiguous. See also “pattern library” and “style guide”. Quite a few people have had a stab at disambiguating those terms, and I think there’s general agreement—a design system is the overall big-picture “thing” that can contain a pattern library, and/or a style guide, and/or much more besides:

None of those great posts attempt to define design ops, and that’s totally fair, because they’re all attempting to define things—style guides, pattern libraries, and design systems—whereas design ops isn’t a thing, it’s a practice. But I do think that design ops follows on nicely from design systems. I think that design ops is the practice of adopting and using a design system.

There are plenty of posts out there about the challenges of getting people to use a design system, and while very few of them use the term design ops, I think that’s what all of them are about:

Clearly design systems and design ops are very closely related: you really can’t have one without the other. What I find interesting is that a lot of the challenges relating to design systems (and pattern libraries, and style guides) might be technical, whereas the challenges of design ops are almost entirely cultural.

I realise that tying design ops directly to design systems is somewhat limiting, and the truth is that design ops can encompass much more. I like Andy’s description:

Design Ops is essentially the practice of reducing operational inefficiencies in the design workflow through process and technological advancements.

Now, in theory, that can encompass any operational stuff—equipment, furniture, software—but in practice, when we’re dealing with design ops, 90% of the time it’s related to a design system. I guess I could use a whole new term (design systems ops?) but I think the term design ops works well …as long as everyone involved is clear on the kind of design ops we’re all talking about.

Getaway

It had been a while since we had a movie night at Clearleft so I organised one for last night. We usually manage to get through two movies, and there’s always a unifying theme decided ahead of time.

For last night, I decided that the broad theme would be …transport. But then, through voting on Slack, people could decide what the specific mode of transport would be. The choices were:

  • taxi,
  • getaway car,
  • truck, or
  • submarine.

Nobody voted for submarines. That’s a shame, but in retrospect it’s easy to understand—submarine films aren’t about transport at all. Quite the opposite. Submarine films are about being trapped in a metal womb/tomb (and many’s the spaceship film that qualifies as a submarine movie).

There were some votes for taxis and trucks, but the getaway car was the winner. I then revealed which films had been pre-selected for each mode of transport.

Taxi

Getaway car

Shorts: Getaway Driver, The Getaway

Truck

Submarine

I thought Baby Driver would be a shoe-in for the first film, but enough people had already seen it quite recently to put it out of the running. We watched Wheelman instead, which was like Locke meets Drive.

So what would the second film be?

Well, some of those films in the full list could potentially fall into more than one category. The taxi in Collateral is (kinda) being used as a getaway car. And if you expand the criterion to getaway vehicle, then Furiosa’s war rig surely counts, right?

Okay, we were just looking for an excuse to watch Fury Road again. I mean, c’mon, it was the black and chrome edition! I had the great fortune of seeing that on the big screen a while back and I’ve been raving about it ever since. Besides, you really don’t need an excuse to rewatch Fury Road. I loved it the first time I saw it, and it just keeps getting better and better each time. The editing! The sound! The world-building!

With every viewing, it feels more and more like the film for our time. It may have been a bit of stretch to watch it under the thematic umbrella of getaway vehicles, but it’s a getaway for our current political climate: instead of the typical plot involving a gang driving at full tilt from a bank heist, imagine one where the gang turns around, ousts the bankers, and replaces the whole banking system with a matriarchal community.

Hope is a mistake”, Max mansplains (maxplains?) to Furiosa at one point. He’s wrong. Judicious hope is what drives us forward (or, this case, back …to the citadel). Watching Fury Road again, I drew hope from the character of Nux. An alt-warboy in thrall to a demagogue and raised on a diet of fake news (Valhalla! V8!) can not only be turned by tenderness, he can become an ally to those working for a better world.

Witness!
