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!

Why Design Systems Fail by Una Kravets

I’m at An Event Apart Boston where Una is about to talk about design systems, following on from Yesenia’s excellent design systems talk. I’m going to attempt to liveblog it…

Una works at the Bustle Digital Group, which publishes a lot of different properties. She used to work at Watson, at Bluemix and at Digital Ocean. They all have something in common (other than having blue in their logos). They all had design systems that failed.

Design systems are so hot right now. They allow us think in a componentised way, and grow quickly. There are plenty of examples out there, like Polaris from Shopify, the Lightning design sytem from Salesforce, Garden from Zendesk, Gov.uk, and Code For America. Check out Anna’s excellent styleguides.io for more examples.

What exactly is a design system?

It’s a broad term. It can be a styleguide or visual pattern library. It can be design tooling (like a Sketch file). It can be a component library. It can be documentation of design or development usage. It can be voice and tone guidelines.

Styleguides

When Una was in College, she had a print rebranding job—letterheads, stationary, etc. She also had to provide design guidelines. She put this design guide on the web. It had colours, heading levels, type, logo treatments, and so on. It wasn’t for an application, but it was a design system.

Design tooling

Primer by Github is a good example of this. You can download pre-made icons, colours, etc.

Component library

This is where you get the code. Una worked on BUI at Digital Ocean, which described the interaction states of each components and how to customise interactions with JavaScript.

Code usage guidelines

AirBnB has a really good example of this. It’s a consistent code style. You can even include it in your build step with eslint-config-airbnb and stylelint-config-airbnb.

Design usage documentation

Carbon by IBM does a great job of this. It describes the criteria for deciding when to use a pattern. It’s driven by user experience considerations. They also have general guidelines on loading in components—empty states, etc. And they include animation guidelines (separately from Carbon), built on the history of IBM’s magnetic tape machines and typewriters.

Voice and tone guidelines

Of course Mailchimp is the classic example here. They break up voice and tone. Voice is not just what the company is, but what the company is not:

  • Fun but not silly,
  • Confident but not cocky,
  • Smart but not stodgy,
  • and so on.

Voiceandtone.com describes the user’s feelings at different points and how to communicate with them. There are guidelines for app users, and guidelines for readers of the company newsletter, and guidelines for readers of the blog, and so on. They even have examples of when things go wrong. The guidelines provide tips on how to help people effectively.

Why do design systems fail?

Una now asks who in the room has ever started a diet. And who has ever finished a diet? (A lot of hands go down).

Nobody uses it

At Digital Ocean, there was a design system called Buoy version 1. Una helped build a design system called Float. There was also a BUI version 2. Buoy was for product, Float was for the marketing site. Classic example of 927. Nobody was using them.

Una checked the CSS of the final output and the design system code only accounted for 28% of the codebase. Most of the CSS was over-riding the CSS in the design system.

Happy design systems scale good standards, unify component styles and code and reduce code cruft. Why were people adding on instead of using the existing sytem? Because everyone was being judged on different metrics. Some teams were judged on shipping features rather than producing clean code. So the advantages of a happy design systems don’t apply to them.

Investment

It’s like going to the gym. Small incremental changes make a big difference over the long term. If you just work out for three months and then stop, you’ll lose all your progress. It’s like that with design systems. They have to stay in sync with the live site. If you don’t keep it up to date, people just won’t use it.

It’s really important to have a solid core. Accessibility needs to be built in from the start. And the design system needs ownership and dedicated commitment. That has to come from the organisation.

You have to start somewhere.

Communication

Communication is multidimensional; it’s not one-way. The design system owner (or team) needs to act as a bridge between designers and developers. Nobody likes to be told what to do. People need to be involved, and feel like their needs are being addressed. Make people feel like they have control over the process …even if they don’t; it’s like perceived performance—this is perceived involvement.

Ask. Listen. Make your users feel heard. Incorporate feedback.

Buy-in

Good communication is important for getting buy-in from the people who will use the design system. You also need buy-in from the product owners.

Showing is more powerful than telling. Hackathans are like candy to a budding design system—a chance to demonstrate the benefits of a design system (and get feedback). After a hackathon at Digital Ocean, everyone was talking about the design system. Weeks afterwards, one of the developers replaced Bootstrap with BUI, removing 20,000 lines of code! After seeing the impact of a design system, the developers will tell their co-workers all about it.

Solid architecture

You need to build with composability and change in mind. Primer, by Github, has a core package, and then add-ons for, say, marketing or product. That separation of concerns is great. BUI used a similar module-based approach: a core codebase, separate from iconography and grid.

Semantic versioning is another important part of having a solid architecture for your design system. You want to be able to push out minor updates without worrying about breaking changes.

Major.Minor.Patch

Use the same convention in your design files, like Sketch.

What about tech stack choice? Every company has different needs, but one thing Una recommends is: don’t wait to namespace! All your components should have some kind of prefix in the class names so they don’t clash with existing CSS.

Una mentions Solid by Buzzfeed, which I personally think is dreadful (count the number of !important declarations—you can call it “immutable” all you want).

AtlasKit by Atlassian goes all in on React. They’re trying to integrate Sketch into it, but design tooling isn’t solved yet (AirBnB are working on this too). We’re still trying to figure out how to merge the worlds of design and code.

Reduce Friction

This is what it’s all about. Using the design system has to be the path of least resistance. If the new design system is harder to use than what people are already doing, they won’t use it.

Provide hooks and tools for the people who will be using the design system. That might be mixins in Sass or it might be a script on a CDN that people can just link to.

Start early, update often. Design systems can be built retrospectively but it’s easier to do it when a new product is being built.

Bugs and cruft always increase over time. You need a mechanism in place to keep on top of it. Not just technical bugs, but visual inconsistencies.

So the five pillars of ensuring a successful design system are:

  1. Investment
  2. Communication
  3. Buy-in
  4. Solid architecture
  5. Reduce friction

When you’re starting, begin with a goal:

We are building a design system because…

Then review what you’ve already got (your existing codebase). For example, if the goal of having a design system is to increase page performance, use Web Page Test to measure how the current site is performing. If the goal is to reduce accessibility problems, use webaim.org to measure the accessibility of your current site (see also: pa11y). If the goal is to reduce the amount of CSS in your codebase, use cssstats.com to test how your current site is doing. Now that you’ve got stats, use them to get buy-in. You can also start by doing an interface inventory. Print out pages and cut them up.

Once you’ve got buy-in and commitment (in writing), then you can make technical decisions.

You can start with your atomic elements. Buttons are like the “Hello world!” of design systems. You’ve colours, type, and different states.

Then you can compose elements by putting the base elements together.

Do you include layout in the system? That’s a challenge, and it depends on your team. If you do include layout, to what extent?

Regardless of layout, you still need to think about space: the space between base elements within a component.

Bake in accessibility: every hover state should have an equal (not opposite) focus state.

Think about states, like loading states.

Then you can start documenting. Then inform the users of the system. Carbon has a dashboard showing which components are new, which components are deprecated, and which components are being updated.

Keep consistent communication. Design and dev communication has to happen. Continuous iteration, support and communication are the most important factors in the success of a design system. Code is only 10% of a sytem.

Also, don’t feel like you need to copy other design systems out there. Your needs are probably very different. As Diana says, comparing your design system to the polished public ones is like comparing your life to someone’s Instagram account. To that end, Una says something potentially contraversial:

You might not need a design sytem.

If you’re the only one at your organisation that cares about the benefits of a design system, you won’t get buy-in, and if you don’t get buy-in, the design system will fail. Maybe there’s something more appropriate for your team? After all, not everyone needs to go to the gym to get fit. There are alternatives.

Find what works for you and keep at it.

Design systems

Talking about scaling design can get very confusing very quickly. There are a bunch of terms that get thrown around: design systems, pattern libraries, style guides, and components.

The generally-accepted definition of a design system is that it’s the outer circle—it encompasses pattern libraries, style guides, and any other artefacts. But there’s something more. Just because you have a collection of design patterns doesn’t mean you have a design system. A system is a framework. It’s a rulebook. It’s what tells you how those patterns work together.

This is something that Cennydd mentioned recently:

Here’s my thing with the modularisation trend in design: where’s the gestalt?

In my mind, the design system is the gestalt. But Cennydd is absolutely right to express concern—I think a lot of people are collecting patterns and calling the resulting collection a design system. No. That’s a pattern library. You still need to have a framework for how to use those patterns.

I understand the urge to fixate on patterns. They’re small enough to be manageable, and they’re tangible—here’s a carousel; here’s a date-picker. But a design system is big and intangible.

Games are great examples of design systems. They’re frameworks. A game is a collection of rules and constraints. You can document those rules and constraints, but you can’t point to something and say, “That is football” or “That is chess” or “That is poker.”

Even though they consist entirely of rules and constraints, football, chess, and poker still produce an almost infinite possibility space. That’s quite overwhelming. So it’s easier for us to grasp instances of football, chess, and poker. We can point to a particular occurrence and say, “That is a game of football”, or “That is a chess match.”

But if you tried to figure out the rules of football, chess, or poker just from watching one particular instance of the game, you’d have your work cut for you. It’s not impossible, but it is challenging.

Likewise, it’s not very useful to create a library of patterns without providing any framework for using those patterns.

I would go so far as to say that the actual code for the patterns is the least important part of a design system (or, certainly, it’s the part that should be most malleable and open to change). It’s more important that the patterns have been identified, named, described, and crucially, accompanied by some kind of guidance on usage.

I could easily imagine using a tool like Fractal to create a library of text snippets with no actual code. Those pieces of text—which provide information on where and when to use a pattern—could be more valuable than providing a snippet of code without any context.

One of the very first large-scale pattern libraries I can remember seeing on the web was Yahoo’s Design Pattern Library. Each pattern outlined

  1. the problem being solved;
  2. when to use this pattern;
  3. when not to use this pattern.

Only then, almost incidentally, did they link off to the code for that pattern. But it was entirely possible to use the system of patterns without ever using that code. The code was just one instance of the pattern. The important part was the framework that helped you understand when and where it was appropriate to use that pattern.

I think we lose sight of the real value of a design system when we focus too much on the components. The components are the trees. The design system is the forest. As Paul asked:

What methodologies might we uncover if we were to focus more on the relationships between components, rather than the components themselves?

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.

Patterns Day videos

Eleven days have passed since Patterns Day. I think I’m starting to go into withdrawal.

Fortunately there’s a way to re-live the glory. Video!

The first video is online now: Laura Elizabeth’s excellent opener. More videos will follow. Keep an eye on this page.

And remember, the audio is already online as a podcast.

Patterns Day speakers

Ticket sales for Patterns Day are going quite, quite briskly. If you’d like to come along, but you don’t yet have a ticket, you might want to remedy that. Especially when you hear about who else is going to be speaking…

Sareh Heidari works at the BBC building websites for a global audience, in as many as twenty different languages. If you want to know about strategies for using CSS at scale, you definitely want to hear this talk. She just stepped off stage at the excellent CSSconf EU in Berlin, and I’m so happy that Sareh’s coming to Brighton!

Patterns Day isn’t the first conference about design systems and pattern libraries on the web. That honour goes to the Clarity conference, organised by the brilliant Jina Anne. I was gutted I couldn’t make it to Clarity last year. By all accounts, it was excellent. When I started to form the vague idea of putting on an event here in the UK, I immediately contacted Jina to make sure she was okay with it—I didn’t want to step on her toes. Not only was she okay with it, but she really wanted to come along to attend. Well, never mind attending, I said, how about speaking?

I couldn’t be happier that Jina agreed to speak. She has had such a huge impact on the world of pattern libraries through her work with the Lightning design system, Clarity, and the Design Systems Slack channel.

The line-up is now complete. Looking at the speakers, I find myself grinning from ear to ear—it’s going to be an honour to introduce each and every one of them.

This is going to be such an excellent day of fun and knowledge. I can’t wait for June 30th!

Fractal ways

24 Ways is back! That’s how we web nerds know that the Christmas season is here. It kicked off this year with a most excellent bit of hardware hacking from Seb: Internet of Stranger Things.

The site is looking lovely as always. There’s also a component library to to accompany it: Bits, the front-end component library for 24 ways. Nice work, courtesy of Paul. (I particularly like the comment component example).

The component library is built with Fractal, the magnificent tool that Mark has open-sourced. We’ve been using at Clearleft for a while now, but we haven’t had a chance to make any of the component libraries public so it’s really great to be able to point to the 24 Ways example. The code is all on Github too.

There’s a really good buzz around Fractal right now. Lots of people in the design systems Slack channel are talking about it. There’s also a dedicated Fractal Slack channel for people getting into the nitty-gritty of using the tool.

If you’re currently wrestling with the challenges of putting a front-end component library together, be sure to give Fractal a whirl.

Code refactoring for America

Here at Clearleft, we’ve been doing some extra work with Code for America following on from our initial deliverables. This makes me happy for a number of reasons:

  1. They’re a great client—really easy-going and fun to work with.
  2. We’ve got Anna back in the office and it’s always nice to have her around.
  3. We get to revisit the styleguide we provided, and test our assumptions.

That last one is important. When we provide a pattern library to a client, we hope that they’ve got everything they need. If we’ve done our job right, then they’ll be able to combine patterns in ways we haven’t foreseen to create entirely new page types.

For the most part, that’s been the case with Code for America. They have a solid set of patterns that are serving them well. But what’s been fascinating is to hear about what it’s like for the people using those patterns…

There’s been a welcome trend in recent years towards extremely robust, maintainable CSS. SMACSS, BEM, OOCSS and other methodologies might differ in their details, but their fundamental approach is pretty similar. The idea is that you apply a very specific class to every element you want to style:

<div class="thingy">
    <ul class="thingy-bit">
        <li class="thingy-bit-item"></li>
        <li class="thingy-bit-item"></li>
    </ul>
    <img class="thingy-wotsit" src="" alt="" />
</div>

That allows you to keep your CSS selectors very short, but very specific:

.thingy {}
.thingy-bit {}
.thingy-bit-item {}
.thingy-wotsit {}

There’s little or no nesting, and you only ever use class selectors. That keeps your CSS nice and clear, and you avoid specificity hell. The catch is that your HTML is necessarily more verbose: you need to explicitly add a class to whatever you want to style.

For most projects—particularly product work (think Twitter, Facebook, etc.)—that’s a completely acceptable trade-off. It’s usually the same developers editing the CSS and the HTML so there’s no problem moving complexity out of CSS and into the markup templates. Even if other people will be entering the actual content into the system, they’ll probably be doing that mediated through a Content Management System, rather than editing HTML directly.

So nine times out of ten, making the HTML more verbose is absolutely the right choice in order to make the CSS more manageable and maintainable. That’s the way we initially built the pattern library for Code for America.

Well, it turns out that the people using the markup patterns aren’t necessarily the same people who would be dealing with the CSS. Also, there isn’t necessarily a CMS involved. Instead, people (volunteers, employees, anyone really) create new pages by copying and pasting the patterns we’ve provided and then editing them.

By optimising on the CSS side of things, we’ve offloaded a lot of complexity onto their shoulders. While it’s fair enough to expect them to understand basic HTML, it’s hardly fair to expect them to learn a whole new vocabulary of thingy and thingy-wotsit class names just to get things to look they way they expect.

Here’s a markup pattern that makes more sense for the people actually dealing with the HTML:

<div class="thingy">
    <ul>
        <li></li>
        <li></li>
    </ul>
    <img src="" alt="" />
</div>

Much clearer. But now the CSS looks like this:

.thingy {}
.thingy ul {}
.thingy li {}
.thingy img {}

Actually it’s probably going to look more complicated than that: more nesting, more element selectors, more “defensive” rules trying to anticipate the kind of markup that might be used in a particular pattern.

It feels really strange for Anna and myself to work with these kind of patterns. All of our experience screams “Don’t do that! Why would you that?” …but in this case, it’s the right thing to do for the people building the actual website.

So please don’t interpret this as me saying “Hey, everyone, this is how you should write your CSS.” I’m not saying this is better or worse than adding lots of classes to your HTML. If anything, this illustrates that there is no one right way to do this.

It’s worth remembering why we’re aiming for maintainability in what we write. It’s not for any technical reason. It’s for people. If those people find it better to deal with simplified CSS with more complex HTML, than the complexity should be in the HTML. But if the priority for those people is to have simple HTML, then more complex CSS may be an acceptable price to pay.

In other words, it depends.

Pattern sharing

Mike has written about the Code for America alpha website that we collaborated on:

We chose to work with ClearLeft because they develop a pattern portfolio (a pattern/style library) which would allow us to scale our work to our Brigades. This unique approach has aligned perfectly with our work style and decentralized organizational structure.

Thankfully, I think the approach of delivering a pattern portfolio (instead of just pages) isn’t so unique these days. Mind you, it still seems to be more common with in-house teams than agencies. The Mailchimp pattern library is a classic example.

But agencies like Paravel are—like Clearleft—delivering systems, not pages. Dave wrote about providing responsive deliverables:

Responsive deliverables should look a lot like fully-functioning Twitter Bootstrap-style systems custom tailored for your clients’ needs.

I think that’s a good way of looking at it: a Bootstrap for every project.

Here’s the front-end style guide for Code for America.

Usually these front-end deliverables will be password-protected on the Clearleft extranet for the client’s eyes only, but Code for America are all about openness, so they’re more than willing to let us share it with the world. That makes me very happy. I remember encouraging the guys at Starbucks to publish their front-end style guide and I’ve written about this spirit of sharing before:

These style guides and pattern libraries aren’t being published in an attempt to provide ready-made solutions—every project should have its own distinct pattern library. Instead, these pattern libraries are being published in a spirit of openness and sharing …a way of saying “Hey, this is what worked for us in these particular circumstances.”

If you’re poking around the Code for America style guide, you’ll notice that it borrows some ideas from the pattern primer idea I published a while back. But in this iteration, the markup is available via a toggle—a nice variation. There’s also a patchwork page that provides a nice glance-able uninterrupted view of the same patterns.

Every project is a learning experience and each front-end style guide gives us ideas about how to do the next one better. In fact, Mark is busy working on better internal tools for creating these kinds of deliverables—something we’ll definitely be sharing. In the meantime, I’ll be encouraging other clients to be as open as Code for America have been in allowing us to share these deliverables.

For more on the usefulness of front-end style guides, be sure to read Paul’s article on style guides for the web, Anna’s classic 24 Ways article, and of course, Anna’s pocket guide from Five Simple Steps.

Coding for America

Back when I was wandering around America in August, I mentioned that I met up with Mike Migurski in San Francisco:

I played truant from UX Week this morning to meet up with Mike for a coffee and a chat at Cafe Vega. We were turfed out when the bearded, baseball-capped, Draplinesque barista announced he had to shut the doors because he needed to “run out for some milk.” So we went around the corner to the Code For America office.

It wasn’t just a social visit. Mike wanted to chat about the possibility of working with Clearleft. The Code for America site was being overhauled. The new site needed to communicate directly with volunteers, rather than simply being a description of what Code for America does. But the site also needed to be able to change and adapt as the organisation’s activities expanded. So what they needed was not a set of page designs; they needed a system of modular components that could be assembled in a variety of ways.

This was music to my ears. This sort of systems-thinking is exactly the kind of work that Clearleft likes to get its teeth into. I showed Mike some of the previous work we had done in creating pattern libraries, and it became pretty clear that this was just what they were looking for.

When I got back to Brighton, Clearleft assembled as small squad to work on the project. Jon would handle the visual design, with the branding work of Dojo4 as a guide. For the front-end coding, we brought in some outside help. Seeing as the main deliverable for this project was going to be a front-end style guide, who better to put that together than the person who literally wrote the book on front-end style guides: Anna.

I’ll go into more detail about the technical side of things on the Clearleft blog (and we’ll publish the pattern library), but for now, let me just say that the project was a lot of fun, mostly because the people we were working with at Code for America—Mike, Dana, and Cyd—were so ridiculously nice and easy-going.

Anna and Jon would start the day by playing the unofficial project theme song and then get down to working side-by-side. By the end of the day here in Brighton, everyone was just getting started in San Francisco. So the daily “stand up” conference call took place at 5:30pm our time; 9:30am their time. The meetings rarely lasted longer than 10 or 15 minutes, but the constant communication throughout the project was invaluable. And the time difference actually worked out quite nicely: we’d tell them what we had been working on during our day, and if we needed anything from them; then they could put that together during their day so it was magically waiting for us by the next morning.

It’ll be a while yet before the new site rolls out, but in the meantime they’ve put together an alpha site—with a suitably “under construction” vibe—so that anyone can help out with the code and content by making contributions to the github repo.

Sharing pattern libraries

I’ve been huffduffing talks from this year’s South by Southwest, revisiting some of the ones I saw and catching up with some of the ones I missed.

There are some really design and development resources in there that I didn’t get to see in person:

One talk I did get to see was Andy’s CSS for Grown Ups: Maturing Best Practices.

CSS for Grown Ups: Maturing Best Practices on Huffduffer

It was excellent.

You can have a look through the slides.

He talks about different approaches to creating maintainable CSS for large-scale projects. He touches on naming conventions for classes, something that Nicolas Gallagher wrote about recently. And while he makes reference to SASS and Compass, Andy makes the compelling point that’s what more interesting than powerful tools is the arrival of powerful approaches like SMACSS and OOCSS.

Over and over again, Andy makes the point that we must think in terms of creating design systems, not simply styling individual pages—something that Paul has also spoken about. One of the most powerful tools for making that change in thinking is in the creation of style guides for the web and Paul has even created blog dedicated to the BBC’s style guide.

Andy referenced the BBC GEL style guide in his talk but pointed out that because it’s published as a PDF rather than markup, it isn’t as powerful as it could be—there’s inevitably a loss of signal when the patterns are translated into HTML and CSS. Someone from the BBC was in the audience, and in the Q and A portion, acknowledged that that was a really good point.

After the talk I got chatting with Lincoln Mongillo who worked on the recent responsive redesign of Starbucks.com. He mentioned that they created a markup and CSS style guide for the project. “You know what would be really cool?” I said. “If you published it!”

Here it is. It’s a comprehensive library of markup patterns; exactly the kind of resource that Anna wrote about in 24 Ways.

In my experience, creating a pattern library for any project is immensely valuable, whether you’re working in a team of two or a team of two hundred. I’ve found they work well as the next step after Style Tiles: a way of translating the visual vocabulary of a site into markup and CSS without getting bogged down in the specifics of page structure or layout (very handy for a Content First approach). The modularity of a pattern library enforces a healthy .

I’m really pleased to see more and more pattern libraries being made public. That’s one of the reasons why I shared my pattern primer and Dan shared his Pears theme for Wordpress:

Breaking interfaces down into patterns has been immensely helpful in learning and re-evaluating the best possible code to implement them.

But Pears isn’t about how I code these patterns—it’s a tool for creating your own.

I love that. These style guides and pattern libraries aren’t being published in an attempt to provide ready-made solutions—every project should have its own distinct pattern library. Instead, these pattern libraries are being published in a spirit of openness and sharing …a way of saying “Hey, this is what worked for us in these particular circumstances.”

For that, I am very grateful.
