Accessibility audits for all

It’s often said that it’s easier to make a fast website than it is to keep a website fast. Things slip through. If you’re not vigilant, performance can erode without you noticing.

It’s a similar story for other invisible but important facets of your website: privacy, security, accessibility. Because they’re hidden from view, you won’t be able to see if there’s a regression.

That’s why it’s a good idea to have regular audits for performance, privacy, security, and accessibility.

I wrote about accessibility testing a while back, and how there’s quite a bit that you can do for yourself before calling in an expert to look at the really gnarly stuff:

When you commission an accessibility audit, you want to make sure you’re getting the most out of it. Don’t squander it on issues that you can catch and fix yourself. Make sure that the bulk of the audit is being spent on the specific issues that are unique to your site.

I recently did an internal audit of the Clearleft website. After writing up the report, I also did a lunch’n’learn to share my methodology. I wanted to show that there’s some low-hanging fruit that pretty much anyone can catch.

To start with, there’s keyboard navigation. Put your mouse and trackpad to one side and use the tab key to navigate around.

Caveat: depending on what browser you’re using, you might need to update some preferences for keyboard navigation to work on links. If you’re using Safari, go to “Preferences”, then “Advanced”, and tick “Press Tab to highlight each item on a web page.”

Tab around and find out. You should see some nice chunky :focus-visible styles on links and form fields.

Here’s something else that anyone can do: zoom in. Increase the magnification to 200%. Everything should scale proportionally. How about 500%? You’ll probably see a mobile-friendly layout. That’s fine. As long as nothing is broken or overlapping, you’re good.

At this point, I reach for some tools. I’ve got some bookmarklets that do similar things: tota11y and ANDI. They both examine the source HTML and CSS to generate reports on structure, headings, images, forms, and so on.

These tools are really useful, but you need to be able to interpret the results. For example, a tool can tell you if an image has no alt text. But it can’t tell you if an image has good or bad alt text.

Likewise, these tools are great for catching colour-contrast issues. But there’s a big difference between a colour-contrast issue on the body copy compared to a colour-contrast issue on one unimportant page element.

I think that demonstrates the most important aspect of any audit: prioritisation.

Finding out that you have accessibility issues isn’t that useful if they’re all presented as an undifferentiated list. What you really need to know are which issues are the most important to fix.

By the way, I really like the way that the Gov.uk team prioritises accessibility concerns:

The team puts accessibility concerns in 2 categories:

  1. Theoretical: A question or statement regarding the accessibility of an implementation within the Design System without evidence of real-world impact.
  2. Evidenced: Sharing new research, data or evidence showing that an implementation within the Design System could cause barriers for disabled people.

The team will usually prioritise evidenced issues and queries over theoretical ones.

When I wrote up my audit for the Clearleft website, I structured it in order of priority. The most important things to fix are at the start of the audit. I also used a simple scale for classifying the severity of issues: low, medium, and high priority.

Thankfully there were no high-priority issues. There were a couple of medium-priority issues. There were plenty of low-priority issues. That’s okay. That’s a pretty good distribution.

If you’re interested, here’s the report I delivered…

Accessibility audit on clearleft.com

Colour contrast

There are a few issues with the pink colour. When it’s used on a grey background, or when it’s used as a background colour for white text, the colour contrast isn’t high enough.

The SVG arrow icon could be improved too.

Recommendations

Medium priority
  • Change the pink colour universally to be darker. The custom property --red is currently rgb(234, 33, 90). Change it to rgb(210, 20, 73) (thanks, James!)
Low priority
  • The SVG arrow icon currently uses currentColor. Consider hardcoding solid black (or a very, very dark grey) instead.

Images

Alt text is improving on the site. There’s reasonable alt text at the top level pages and the first screen’s worth of case studies and blog posts. I made a sweep through these pages a while back to improve the alt text but I haven’t done older blog posts and case studies.

Recommendations

Medium priority
  • Make a sweep of older blog posts and case studies and fix alt text.
Low priority
  • Images on the contact page have alt text that starts with “A photo of…” — this is redundant and can be removed.

Headings

The site is using headings sensibly. Sometimes the nesting of headings isn’t perfect, but this is a low priority issue. For example, on the contact page there’s an h1 followed by two h3s. In theory this isn’t correct. In practice (for screen reader users) it’s not an issue.

Recommendations

Low priority
  • On the home page, “UX London 2023” should probably be h3 instead of h1.
  • On the case studies index page we’re currently using h3 headings for the industry sector (“Charities”, “Education” etc.) but these should probably not be headings at all. On the blog index page we use a class “Tags” for a similar purpose. Consider reusing that pattern on the case studies index page.
  • On the about index page, “We’re driven to be” is an h3 and the subsequent three headings are h2s. Ideally this would be reversed: a single h2 followed by three h3s.

Link text

Sometimes the same text is used for different links.

Recommendations

Low priority
  • On the home page the text “Read the case study” is re-used for multiple links. It would be better if each link were different e.g. “Read about The Natural History Museum.”

Forms

The only form on the site is the newsletter sign-up form. It’s marked up pretty well: the input has an associated label, although a visible (clickable) label would be better.

Tabbing order

The site doesn’t use JavaScript to mess with tabbing order for keyboard users. The source order of elements in the markup generally makes sense so all is good.

The focus styles are nice and clear too!

Structure

The site is using HTML landmark elements sensibly (header, nav, main, footer, etc.).

Five questions

In just a couple of weeks, I’ll be heading to Bristol for Pixel Pioneers. The line-up looks really, really good …with the glaring exception of the opening talk, which I’ll be delivering. But once that’s done, I’m very much looking forward to enjoying the rest of the day’s talks.

There are still tickets available if you fancy joining me.

This will be my second time speaking at this conference. I spoke at the inaugural conference back in 2017 when I gave a talk called Evaluating Technology. This time my talk is called Declarative Design.

A few weeks back, Oliver asked me some questions about my upcoming talk. I figured I’d post my answers here…

Welcome back to Pixel Pioneers! You return with another keynote - how do you manage to stay so ever-enthusiastic about designing for the web?

Well, I’d say my enthusiasm is mixed with frustration. And that’s always been the case. Just as I’ve always found new things that excite me about the World Wide Web, there are just as many things that upset me.

But that’s okay. Both forces can be motivating. When I find myself writing a blog post or preparing a talk, the impetus might be “This is so cool! Check this out!” or it might be “This is so maddening! What’s happening!?” …or perhaps a mix of both.

But to answer your question, the World Wide Web never stays still so there’s always something to get excited about. Equally, the longer the web exists, the more sense it makes to examine the fundamental bedrock—HTML, accessibility,progressive enhancement—and see how they’re just as important as ever. And that’s also something to get excited about!

Without too many spoilers, what can we expect to take away from your talk?

I’m hoping to provide people with a lens that they can use to examine their tools, processes, and approaches to designing for the web. It’s a fairly crude lens—it divides the world into a binary split that I’ve borrowed from the world of programming; imperative and declarative languages. But it’s a surprisingly thought-provoking angle.

Along the way I’ll also be pointing out some of the incredible things that we can do with CSS now. In the past few years there’s been an explosion in capabilities.

But this won’t be a code-heavy presentation. It’s mostly about the ideas. I’ll be referencing some projects by other people that I’m very excited by.

What other web design and development tools, techniques and technologies are you currently most excited about?

Outside of the world of CSS—which is definitely where a lot of the most exciting developments are happening—I’m really interested in the View Transitions API. If it delivers on its promise, it could be a very useful nail in the coffin of uneccessary single page apps. But I’m a little nervous. Right now the implementation only works for single page apps, which makes it an incentive to use that model. I really, really hope that the multipage version ships soon.

But honestly, I probably get most excited about discovering some aspect of HTML that I wasn’t aware of. Even after all these years the language can still surprise me.

And on the flipside, what bugs you most about the web at the moment?

How much time have you got?

Seriously though, the thing that’s really bugged me for the past decade is the increasing complexity of “modern” frontend development when it isn’t driven by user needs. Yes, I’m talking about JavaScript frameworks like React and the assumption that everything should be a single page app.

Honestly, the mindset became so ubiquitous that I felt like I must be missing something. But no, the situation really has spiralled out of control, much to the detriment of end users.

Luckily we’re starting to see the pendulum swing back. The proponents of trickle-down developer convenience are having to finally admit that it’s bollocks.

I don’t care if the move back to making websites is re-labelled as “isomorphic server-rendered multi-page apps.” As long as we make sensible architectural decisions, that’s all that matters.

What’s next, Jeremy?

Right now I’m curating the line-up for this year’s UX London conference which is the week after Pixel Pioneers. As you know, conference curation is a lot of work, but it’s also very rewarding. I’m really proud of the line-up.

It’s been a while since the last season of the Clearleft podcast. I hope to remedy that soon. It takes a lot of effort to make even one episode, but again, it’s very rewarding.

Add view transitions to your website

I must admit, when Jake told me he was leaving Google, I got very worried about the future of the View Transitions API.

To recap: Chrome shipped support for the API, but only for single page apps. That had me worried:

If the View Transitions API works across page navigations, it could be the single best thing to happen to the web in years.

If the View Transitions API only works for single page apps, it could be the single worst thing to happen to the web in years.

Well, the multi-page version still hasn’t yet shipped in Chrome stable, but it is available in Chrome Canary behind a flag, so it looks like it’s almost here!

Robin took the words out of my mouth:

Anyway, even this cynical jerk is excited about this thing.

Are you the kind of person who flips feature flags on in nightly builds to test new APIs?

Me neither.

But I made an exception for the View Transitions API. So did Dave:

I think the most telling predictor for the success of the multi-page View Transitions API – compared to all other proposals and solutions that have come before it – is that I actually implemented this one. Despite animations being my bread and butter for many years, I couldn’t be arsed to even try any of the previous generation of tools.

Dave’s post is an excellent step-by-step introduction to using view transitions on your website. To recap:

Enable these two flags in Chrome Canary:

chrome://flags#view-transition
chrome://flags#view-transition-on-navigation

Then add this meta element to the head of your website:

<meta name="view-transition" content="same-origin">

You could stop there. If you navigate around your site, you’ll see that the navigations now fade in and out nicely from one page to another.

But the real power comes with transitioning page elements. Basically, you want to say “this element on this page should morph into that element on that page.” And when I say morph, I mean morph. As Dave puts it:

Behind the scenes the browser is rasterizing (read: making an image of) the before and after states of the DOM elements you’re transitioning. The browser figures out the differences between those two snapshots and tweens between them similar to Apple Keynote’s “Magic Morph” feature, the liquid metal T-1000 from Terminator 2: Judgement Day, or the 1980s cartoon series Turbo Teen.

If those references are lost on you, how about the popular kids book series Animorphs?

Some classic examples would be:

  • A thumbnail of a video on one page morphs into the full-size video on the next page.
  • A headline and snippet of an article on one page morphs into the full article on the next page.

I’ve added view transitions to The Session. Where I’ve got index pages with lists of titles, each title morphs into the heading on the next page.

Again, Dave’s post was really useful here. Each transition needs a unique name, so I used Dave’s trick of naming each transition with the ID of the individual item being linked to.

In the recordings section, for example, there might be a link like this on the index page:

<a href="/recordings/7812" style="view-transition-name: recording-7812">The Banks Of The Moy</a>

Which, if you click on it, takes you to the page with this heading:

<h1><span style="view-transition-name: recording-7812">The Banks Of The Moy</span></h1>

Why the span? Well, like Dave, I noticed some weird tweening happening between block and inline elements. Dave solved the problem with width: fit-content on the block-level element. I just stuck in an extra inline element.

Anyway, the important thing is that the name of the view transition matches: recording-7812.

I also added a view transition to pages that have maps. The position of the map might change from page to page. Now there’s a nice little animation as you move from one page with a map to another page with a map.

thesession.org View Transitions

That’s all good, but I found myself wishing that I could just have those enhancements. Every single navigation on the site was triggering a fade in and out—the default animation. I wondered if there was a way to switch off the default fading.

There is! That default animation is happening on a view transition named root. You can get rid of it with this snippet of CSS:

::view-transition-image-pair(root) {
  isolation: auto;
}
::view-transition-old(root),
::view-transition-new(root) {
  animation: none;
  mix-blend-mode: normal;
  display: block;
}

Voila! Now only the view transitions that you name yourself will get applied.

You can adjust the timing, the easing, and the animation properites of your view transitions. Personally, I was happy with the default morph.

In fact, that’s one of the things I like about this API. It’s another good example of declarative design. I say what I want to happen, but I don’t need to specify the details. I’ll let the browser figure all that out.

That’s what’s got me so excited about this API. Yes, it’s powerful. But just as important, it’s got a very low barrier to entry.

Chris has gathered a bunch of examples together in his post Early Days Examples of View Transitions. Have a look around to get some ideas.

If you like what you see, I highly encourage you to add view transitions to your website now.

“But wait,” I hear you cry, “this isn’t supported in any public-facing browser yet!”

To which, I respond “So what?” It’s a perfect example of progressive enhancement. Adding one meta element and a smidgen of CSS will do absolutely no harm to your website. And while no-one will see your lovely view transitions yet, once browsers do start shipping with support for the API, your site will automatically get better.

Your website will be enhanced. Progressively.

Update: Simon Pieters quite rightly warns against adding view transitions to live sites before the API is done:

in general, using features before they ship in a browser isn’t a great idea since it can poison the feature with legacy content that might break when the feature is enabled. This has happened several times and renames or so were needed.

Good point. I must temper my excitement with pragmatism. Let me amend my advice:

I highly encourage you to experiment with view transitions on your website now.

Talks and workshops at UX London 2023

Back in November of last year I announced that UX London would be returning in 2023 and that I’d be curating the line-up again. That’s where I’ve been putting a lot of my energy over the last six months.

The line-up is complete. If I step back and try to evaluate it objectively, I’ve gotta say …hot damn, that’s a fine roster of speakers!

Imran Afzal, Vimla Appadoo, Daniel Burka, Trine Falbe, Vitaly Friedman, Mansi Gupta, Stephen Hay, Asia Hoe, Amy Hupe, Paul Robert Lloyd, Stacey Mendez, Ignacia Orellana, Stefanie Posavec, Hannah Smith, and David Dylan Thomas.

Take a look at the complete schedule—a terrific mix of thought-provoking talks and practical hands-on workshops.

On day one, you’ve got these talks:

Then on day two:

And that’s just the talks! You’ve also got these four excellent workshops on both days:

That’s a lot of great stuff packed into two days!

In case you haven’t guessed, I am very excited about this year’s UX London. I would love to see you there.

As an appreciation for you putting up with my child-like excitement, I’d like to share a discount code with you. You can get 20%—that’s one fifth!—off the ticket price using the code CLEARLEFT20.

But note that the standard ticket pricing ends on Friday, May 26th so use that code in the next week to get the most bang for your buck. After that, there’ll only be last-chance tickets, which cost more.

Looking forward to seeing you at Tobacco Dock on June 22nd and 23rd!

Nailspotting

I’m sure you’ve heard the law of the instrument: when all you have is a hammer, everything looks like a nail.

There’s another side to it. If you’re selling hammers, you’ll depict a world full of nails.

Recent hammers include cryptobollocks and virtual reality. It wasn’t enough for blockchains and the metaverse to be potentially useful for some situations; they staked their reputations on being utterly transformative, disrupting absolutely every facet of life.

This kind of hype is a terrible strategy in the long-term. But if you can convince enough people in the short term, you can make a killing on the stock market. In truth, the technology itself is superfluous. It’s the hype that matters. And if the hype is over-inflated enough, you can even get your critics to do your work for you, broadcasting their fears about these supposedly world-changing technologies.

You’d think we’d learn. If an industry cries wolf enough times, surely we’d become less trusting of extraordinary claims. But the tech industry continues to cry wolf—or rather, “hammer!”—at regular intervals.

The latest hammer is machine learning, usually—incorrectly—referred to as Artificial Intelligence. What makes this hype cycle particularly infuriating is that there are genuine use cases. There are some nails for this hammer. They’re just not as plentiful as the breathless hype—both positive and negative—would have you believe.

When I was hosting the DiBi conference last week, there was a little section on generative “AI” tools. Matt Garbutt covered the visual side, demoing tools like Midjourney. Scott Salisbury covered the text side, showing how you can generate code. Afterwards we had a panel discussion.

During the panel I asked some fairly straightforward questions that nobody could answer. Who owns the input (the data used by these generative tools)? Who owns the output?

On the whole, it stayed quite grounded and mercifully free of hyperbole. Both speakers were treating the current crop of technologies as tools. Everyone agreed we were on the hype cycle, probably the peak of inflated expectations, looking forward to reaching the plateau of productivity.

Scott explicitly warned people off using generative tools for production code. His advice was to stick to side projects for now.

Matt took a closer look at where these tools could fit into your day-to-day design work. Mostly it was pretty sensible, except when he suggested that there could be any merit to using these tools as a replacement for user testing. That’s a terrible idea. A classic hammer/nail mismatch.

I think I moderated the panel reasonably well, but I have one regret. I wish I had first read Baldur Bjarnason’s new book, The Intelligence Illusion. I started reading it on the train journey back from Edinburgh but it would have been perfect for the panel.

The Intelligence Illusion is very level-headed. It is neither pro- nor anti-AI. Instead it takes a pragmatic look at both the benefits and the risks of using these tools in your business.

It has excellent advice for spotting genuine nails. For example:

Generative AI has impressive capabilities for converting and modifying seemingly unstructured data, such as prose, images, and audio. Using these tools for this purpose has less copyright risk, fewer legal risks, and is less error prone than using it to generate original output.

Think about transcripts of videos or podcasts—an excellent use of this technology. As Baldur puts it:

The safest and, probably, the most productive way to use generative AI is to not use it as generative AI. Instead, use it to explain, convert, or modify.

He also says:

Prefer internal tools over externally-facing chatbots.

That chimes with what I’ve been seeing. The most interesting uses of this technology that I’ve seen involve a constrained dataset. Like the way Luke trained a language model on his own content to create a useful chat interface.

Anyway, The Intelligence Illusion is full of practical down-to-earth advice based on plenty of research backed up with copious citations. I’m only halfway through it and it’s already helped me separate the hype from the reality.

Hosting DIBI

I was up in Edinburgh for the past few days at the Design It; Build It conference.

I was supposed to come back on Saturday but then the train strikes were announced so I changed my travel plans to avoid crossing a picket line, which gave me an extra day to explore Auld Reekie.

I spoke at DIBI last year so this time I was there in a different capacity. I was the host. That meant introducing the speakers and asking them questions after their talks.

I’m used to hosting events now, what with UX London and Leading Design. But I still get nervous beforehand. At least with a talk you can rehearse and practice. With hosting, it’s all about being nimble and thinking on your feet.

I had to pay extra close attention to each talk, scribbling down potential questions to ask. It’s similar to the feeling I get when I’m liveblogging talks.

There were some line-up changes and schedule adjustments along the way, but everything went super smoothly. I pride myself on running a tight ship so the timings were spot-on.

When it came to the questions, I tried to probe under the skin of each presentation. For some talks, that involved talking shop—the finer points of user research or the design process, say. But for the big-picture talks, I made sure to get each speaker to defend their position. So after Dan Makoski’s kumbaya-under-capitalism talk, I gave him a good grilling. Same with Philip Lockwood-Holmes who gave me permission beforehand to be merciless with him.

It was all quite entertaining. Alas, I think I may have put the fear of God into the other speakers who saw me channeling my inner Jeremy Paxman. But they needn’t have worried. I also lobbed some softballs. Like when I asked Levon Sharrow from Patagonia if there was such thing as ethical consumption under capitalism.

I had fun, but I was also aware of that fine line between being clever and being an asshole. Even though part of my role was to play devil’s advocate, I tried to make sure I was never punching down.

All in all, an excellent couple of days spent in good company.

Hosting was hard work, but very rewarding. I’ve come to realise it’s one of those activities that comes relatively easy to me, but it is very hard (and stressful) for others. And I’m pretty gosh-darned good at it too, false modesty bedamned.

So if you’re running an event but the thought of hosting it fills you with dread, we should talk.

Tragedy

There are two kinds of time-travel stories.

There are time-travel stories that explore the many-worlds hypothesis. Going back in time and making a change forks the universe. But the universe is constantly forking anyway. So effectively the time travel is a kind of universe-hopping (there’s a big crossover here with the alternative history subgenre).

The problem with multiverse stories is that there’s always a reset available. No matter how bad things get, there’s a parallel universe where everything is hunky dory.

The other kind of time travel story explores the idea of a block universe. There is one single timeline.

This is what you’ll find in Tenet, for example, or for a beautiful reduced test case, the Ted Chiang short story What’s Expected Of Us. That gets straight to the heart of the biggest implication of a block universe—the lack of free will.

There’s no changing what has happened or what will happen. In fact, the very act of trying to change the past often turns out to be the cause of what you’re trying to prevent in the present (like in Twelve Monkeys).

I’ve often referred to these single-timeline stories as being like Greek tragedies. But only recently—as I’ve been reading quite a bit of Greek mythology—have I realised that the reverse is also true:

Greek tragedies are time-travel stories.

Hear me out…

Time-travel stories aren’t actually about physically travelling in time. That’s just a convenience for the important part—information travelling in time. That’s at the heart of most time-travel stories; informaton from the future travelling back to the past.

William Gibson’s The Peripheral—very much a many-worlds story with its alternate universe “stubs”—takes this to its extreme. Nothing phyiscal ever travels in time. But in an age of telecommuting, nothing has to. Our time travellers are remote workers.

That book also highlights the power dynamics inherent in information wealth. Knowledge of the future gives you an advantage that you can exploit in the past. This is what Mark Twain’s Connecticut yankee does in King Arthur’s court.

This power dynamic is brilliantly inverted in Octavia Butler’s brilliant Kindred. No amount of information can help you if your place in society is determined by the colour of your skin.

Anyway, the point is that information flow is what matters in time-travel stories. Therefore any story where information travels backwards in time is a time-travel story.

That includes any story with a prophecy. A prophecy is information about the future, like:

Oedipus will kill his father and marry his mother.

You can try to change your fate, but you’ll just end up triggering it instead.

Greek tragedies are time-travel stories.

Innovation

I did an episode of the Clearleft podcast on innovation a while back:

Everyone wants to be innovative …but no one wants to take risks.

The word innovation is often bandied about in an unquestioned positive way. But if we acknowledge that innovation is—by definition—risky, then the exhortations sound less positive.

“We provide innovative solutions for businesses!” becomes “We provide risky solutions for businesses!”

I was reminded of this when I saw the website for the Podcast Standards Project. The original text on the website described the project as:

…a grassroots coalition working to establish modern, open standards, to enable innovation in the podcast industry.

I pushed back on that wording (partly because I’ve seen the word “innovation” used as a smoke screen for user-hostile practices like tracking and surveillance). The wording has since changed to:

…a grassroots coalition dedicated to creating standards and practices that improve the open podcasting ecosystem for both listeners and creators.

That’s better. It’s more precise.

Am I nitpicking? Only if you think that “innovation” and “improvement” are synonyms. I don’t think they are.

Innovation implies change. Improvement implies positive change.

Not all change is positive. Not all innovation is positive.

Innovation goes hand in hand with disruption. Again, disruption involves change. But not necessarily positive change.

Think about the antonyms of change and disruption: stasis and stability. Those words don’t sound very exciting, but in some arenas they’re exactly what you should be aiming for; arenas like infrastructure or standards.

Not to get all pace layers-y here, but it seems to me that every endeavour has a sweet spot for innovation. For some projects, too little innovation is bad. For others, too much innovation is worse.

The trick is knowing which kind of project you’re working on.

(As a side note, I think some people use the word innovation to describe the generative, divergent phase of a design project: “how might we come up with innovative new approaches?” But we already have a word to describe the practice of generating novel and interesting ideas. That word isn’t innovation. It’s creativity.)

The intersectionality of web performance

Web performance is an unalloyed good. No one has ever complained that a website is too fast.

So the benefit is pretty obvious. Users like fast websites. But there are other benefits to web performance. And they don’t all get equal airtime.

Business

A lot of good web performance practices come down to the first half of Postel’s Law: be conservative in what send. Images, fonts, JavaScript …remove what you don’t need and optimise the hell out of what’s left.

That can translate to savings. If you’re paying for the bandwidth every time a hefty file is downloaded, your monthly bill could get pretty big.

So apart from the indirect business benefits of happy users converting to happy customers, there can be a real nuts’n’bolts bottom-line saving to be made by having a snappy website.

Sustainability

This is related to the cost-savings benefit. If you’re shipping less stuff down the wire, and you’re optimising what you do send, then there’s less energy required.

Whether less energy directly translates to a smaller carbon footprint depends on how the energy is being generated. If your servers are running on 100% renewable energy sources, then reducing the output of your responses won’t reduce your carbon footprint.

But there’s an energy cost at the other end too. Think of all the devices making requests to your server. If you’re making those devices work hard—by downloading, parsing, executing lots of JavaScript, for example—then you’re draining battery life. And you can’t guarantee that the battery will be replenished from renewable energy sources.

That’s why sites like the website carbon calculator have so much crossover with web performance:

From data centres to transmission networks to the billions of connected devices that we hold in our hands, it is all consuming electricity, and in turn producing carbon emissions equal to or greater than the global aviation industry. Yikes!

Inclusivity

There comes a point when a slow website isn’t just inconvenient, it’s inaccessible.

I’ve always liked the German phrase for accessible: barrierefrei—free of barriers. With every file you add to a website’s dependencies, you’re adding one more barrier. Eventually the barrier is insurmountable for people with older devices or slower internet connections. If they can no longer access your website, your website is quite literally inaccessible.

Making the case

I’ve noticed that when it comes to making the argument in favour of better web performance, people often default to the business benefits.

I get it. We’re always being told to speak the language of business. The psychology seems pretty straightforward; if you think that the people you’re trying to convince are mostly concerned with the bottom line, use the language of commerce to change their minds.

But that’s always felt reductive to me.

Sure, those people almost certainly do care about the business. Who doesn’t? But they’re also humans. I feel like if really want to convince them, speak to their hearts. Show them the bigger picture.

Eliel Saarinen said:

Always design a thing by considering it in its next larger context; a chair in a room, a room in a house, a house in an environment, an environment in a city plan.

I think the same could apply to making the case for web performance. Don’t stop at the obvious benefits. Go wider. Show the big-picture implications.

Spring

Spring is arriving. It’s just taking its time.

There are little signs. Buds on the trees. The first asparagus of the year. Daffodils. Changing the clocks. A stretch in the evenings. But the weather remains, for the most part, chilly and grim.

Reality is refusing to behave like a fast-forward montage leading up to to a single day when you throw open the curtains and springtime is suddenly there in all its glory.

That’s okay. I can wait. I’ve had a lot of practice over the past three years. We all have. Staying home, biding time, saving lives.

But hunkering down during The Situation isn’t like taking shelter during an air raid. There isn’t a signal that sounds to indicate “all clear!” It’s more like going from Winter to Spring. It’s slow, almost impercetible. But it is happening.

I’ve noticed a subtle change in my risk assessment over the past few months. I still think about COVID-19. I still factor it into my calculations. But it’s no longer the first thing I think of.

That’s a subtle change. It doesn’t seem like that long ago when COVID was at the forefront of my mind, especially if I was weighing up an excursion. Is it worth going to that restaurant? How badly do I want to go to that gig? Should I go to that conference?

Now I find myself thinking of COVID as less of a factor in my decision-making. It’s still there, but it has slowly slipped down the ranking.

I know that other people feel differently. For some people, COVID slipped out of their minds long ago. For others, it’s still very much front and centre. There isn’t a consensus on how to evaluate the risks. Like I said:

It’s like when you’re driving and you think that everyone going faster than you is a maniac, and everyone going slower than you is an idiot.

COVID-19 isn’t going away. But perhaps The Situation is.

The Situation has been gradually fading away. There isn’t a single moment where, from one day to the next, we can say “this marks the point where The Situation ended.” Even if there were, it would be a different moment for everyone.

As of today, the COVID-19 app officially stops working. Perhaps today is as good a day as any to say Spring has arrived. The season of rebirth.
