I’m more proud of these 128 kilobytes than anything I’ve built since | by Mike Hall | Jul, 2025 | Medium

I don’t normally link to articles on Medium—I respect you too much—and I do wish this were written on Mike Hall’s own site, but this is just too good not to share.

And don’t dismiss this as a nostalgiac case study from the past:

At no point did the constraints make the product feel compromised. Users on modern devices got a smooth experience and instant feedback, while those on older devices got fast, reliable functionality. Users on feature phones got the same core experience without the bells and whistles.

The constraints forced us to solve problems in ways we wouldn’t have considered otherwise. Without those constraints, we could have just thrown bytes at the problem, but with them every feature had to justify itself. Core functionality had to work everywhere, and without JavaScript crutches proper markup became essential.

This experience changed how I approach design problems. Constraints aren’t a straitjacket, keeping us from doing our best work; they are the foundation that makes innovation possible. When you have to work within severe limitations, you find elegant solutions that scale beyond those limitations.

Introducing: Webbed Sites (Webbed Briefs)

I heard you like divs…

Today is Global Accessibility Awareness Day:

The purpose of GAAD is to get everyone talking, thinking and learning about digital access and inclusion, and the more than One Billion people with disabilities/impairments.

Awareness is good. It’s necessary. But it’s not sufficient.

Accessibility, like sustainability and equality, is the kind of thing that most businesses will put at the end of sentences that begin “We are committed to…”

It’s what happens next that matters. How does that declared commitment—that awareness—turn into action?

In the worst-case scenario, an organisation might reach for an accessibility overlay. Who can blame them? They care about accessibility. They want to do something. This is something.

Good intentions alone can result in an inaccessible website. That’s why I think there’s another level of awareness that’s equally important. Designers and developers need to be aware of what they can actually do in service of accessibility.

Fortunately that’s not an onerous expectation. It doesn’t take long to grasp the importance of having good colour contrast or using the right HTML elements.

An awareness of HTML is like a superpower when it comes to accessibility. Like I wrote in the foreword to the Web Accessibility Cookbook by O’Reilly:

It’s supposed to be an accessibility cookbook but it’s also one of the best HTML tutorials you’ll ever find. Come for the accessibility recipe; stay for the deep understanding of markup.

The challenge is that HTML is hidden. Like Cassie said in the accessibility episode of The Clearleft Podcast:

You get JavaScript errors if you do that wrong and you can see if your CSS is broken, but you don’t really have that with accessibility. It’s not as obvious when you’ve got something wrong.

We are biased towards what we can see—hierarchy, layout, imagery, widgets. Those are the outputs. When it comes to accessibility, what matters is how those outputs are generated. Is that button actually a button element or is it a div? Is that heading actually an h1 or is it another div?

This isn’t about the semantics of HTML. This is about the UX of HTML:

Instead of explaining the meaning of a certain element, I show them what it does.

That’s the kind of awareness I’m talking about.

One way of gaining this awareness is to get a feel for using a screen reader.

The name is a bit of a misnomer. Reading the text on screen is the least important thing that the software does. The really important thing that a screen reader does is convey the structure of what’s on screen.

Friend of Clearleft, Jamie Knight very generously spent an hour of his time this week showing everyone the basics of using VoiceOver on a Mac (there’s a great short video by Ethan that also covers this).

Using the rotor, everyone was able to explore what’s under the hood of a web page; all the headings, the text of all the links, the different regions of the page.

That’s not going to turn anyone into an accessibility expert overnight, but it gave everyone an awareness of how much the HTML matters.

Mind you, accessibility is a much bigger field than just screen readers.

Fred recently hosted a terrific panel called Is neurodiversity the next frontier of accessibility in UX design?—well worth a watch!

One of those panelists—Craig Abbott—is speaking on day two of UX London next month. His talk has the magnificent title, Accessibility is a design problem:

I spend a bit of time covering some misconceptions about accessibility, who is responsible for it, and why it’s important that we design for it up front. It also includes real-world examples where design has impacted accessibility, before moving onto lots of practical guidance on what to be aware of and how to design for many different accessibility issues.

Get yourself a ticket and get ready for some practical accessibility awareness.

Are you looking for a book that explains why you should care about web accessibility?

This is not that book.

Manuel Matuzović has too much respect for your intelligence to waste time trying to convince you of something you already know. You already know that web accessibility is important.

What you really need is a guidebook, a handy companion to show you the way through a tangled landscape.

This is that book.

If you want, you can read it cover to cover. That’s what I did, and I enjoyed every moment of the journey.

But you might not have time for that. That’s okay. The way that this book is subdivided means you can deep into any chapter and it will make perfect sense by itself. It really is like a cookbook. Every chapter is like a standalone recipe.

Whether you read this book linearly or dip in and out of it is up to you. Either way, Manuel is going to massage your brain until something new takes shape in there. An understanding. Not just an understanding of web accessibility, but of the very building blocks of the web itself.

See, that’s the sneaky trick that Manuel has managed with this book. It’s supposed to be an accessibility cookbook but it’s also one of the best HTML tutorials you’ll ever find. Come for the accessibility recipe; stay for the deep understanding of markup.

Best of all, Manuel manages to do all this without wasting a word. Again, he has too much respect for you to waste your time. The only unnecessary words in your Accessibility Cookbook are the ones you’re reading now. So I’m going to follow Manuel’s example, respect your time, and let you explore this magnificent book for yourself.

Enjoy the journey!

This is a lovely, lovely talk from Léonie!

Hire HTML and CSS people

Every problem at every company I’ve ever worked at eventually boils down to “please dear god can we just hire people who know how to write HTML and CSS.”

80 / 20 accessibility · marcus.io

So my observation is that 80% of the subject of accessibility consists of fairly simple basics that can probably be learnt in 20% of the time available. The remaining 20% are the difficult situations, edge cases, assistive technology support gaps and corners of specialised knowledge, but these are extrapolated to 100% of the subject, giving it a bad, anxiety-inducing and difficult reputation overall.

How do we build the future with AI? – Chelsea Troy

This is the transcript of a fantastic talk called “The Tools We Still Need to Build with AI.”

Absorb every word!

Web Content Accessibility Guidelines—or WCAG—looks very daunting. It’s a lot to take in. It’s kind of overwhelming. It’s hard to know where to start.

I recommend taking a deep breath and focusing on the four principles of accessibility. Together they spell out the cutesy acronym POUR:

1. Perceivable
2. Operable
3. Understandable
4. Robust

A lot of work has gone into distilling WCAG down to these four guidelines. Here’s how I apply them in my work…

Perceivable

I interpret this as:

Content will be legible, regardless of how it is accessed.

For example:

• The contrast between background and foreground colours will meet the ratios defined in WCAG 2.
• Content will be grouped into semantically-sensible HTML regions such as navigation, main, footer, etc.

Operable

I interpret this as:

Core functionality will be available, regardless of how it is accessed.

For example:

• I will ensure that interactive controls such as links and form inputs will be navigable with a keyboard.
• Every form control will be labelled, ideally with a visible label.

Understandable

I interpret this as:

Content will make sense, regardless of how it is accessed.

For example:

• Images will have meaningful alternative text.
• I will make sensible use of heading levels.

This is where it starts to get quite collaboritive. Working at an agency, there will some parts of website creation and maintenance that will require ongoing accessibility knowledge even when our work is finished.

For example:

• Images uploaded through a content management system will need sensible alternative text.
• Articles uploaded through a content management system will need sensible heading levels.

Robust

I interpret this as:

Content and core functionality will still work, regardless of how it is accessed.

For example:

• Drop-down controls will use the HTML select element rather than a more fragile imitation.
• I will only use JavaScript to provide functionality that isn’t possible with HTML and CSS alone.

If you’re applying a mindset of progressive enhancement, this part comes for you. If you take a different approach, you’re going to have a bad time.

Taken together, these four guidelines will get you very far without having to dive too deeply into the rest of WCAG.

The Web Accessibility Cookbook

Manu’s book is available to pre-order now. I’ve had a sneak peek and I highly recommend it!

You’ll learn how to build common patterns written accessibly in HTML, CSS, and JavaScript. You’ll also start to understand how good and bad practices affect people, especially those with disabilities.

Manifesto for a Humane Web

I endorse this message.

This manifesto is intended as a personal response to the current state of the web. It is a statement of intent and a call to arms, inviting you, the reader, to go forth and build humane websites, and to resist the erosion of the web we know and love.

Faster Connectivity !== Faster Websites - Jim Nielsen’s Blog

The bar to overriding browser defaults should be way higher than it is.

Amen!

I’m at day two of Indie Web Camp Brighton.

Day one was excellent. It was really hard to choose which sessions to go to because they all sounded interesting. That’s a good problem to have.

I ended up participating in:

• a session on POSSE,
• a session on NFC tags,
• a session on writing, and
• a session on testing your website that was hosted by Ros

In that testing session I shared some of the bookmarklets I use regularly.

Bookmarklets? They’re bookmarks that sit in the toolbar of your desktop browser. Just like any other bookmark, they’re links. The difference is that these links begin with javascript: rather than http. That means you can put programmatic instructions inside the link. Click the bookmark and the JavaScript gets executed.

In my mind, there are two different approaches to making a bookmarklet. One kind of bookmarklet contains lots of clever JavaScript—that’s where the smart stuff happens. The other kind of bookmarklet is deliberately dumb. All they do is take the URL of the current page and pass it to another service—that’s where the smart stuff happens.

I like that second kind of bookmarklet.

Here are some bookmarklets I’ve made. You can drag any of them up to the toolbar of your browser. Or you could create a folder called, say, “bookmarklets”, and drag these links up there.

Validation: This bookmarklet will validate the HTML of whatever page you’re on.

Validate HTML

Carbon: This bookmarklet will run the domain through the website carbon calculator.

Calculate carbon

Accessibility: This bookmarklet will run the current page through the Website Accessibility Evaluation Tools.

WAVE

Performance: This bookmarklet will take the current page and it run it through PageSpeed Insights, which includes a Lighthouse test.

PageSpeed

HTTPS: This bookmarklet will run your site through the SSL checker from SSL Labs.

SSL Report

Headers: This bookmarklet will test the security headers on your website.

Security Headers

Drag any of those links to your browser’s toolbar to “install” them. If you don’t like one, you can delete it the same way you can delete any other bookmark.

On Nielsen’s ideas about generative UI for resolving accessibility

Per Axbom quite rightly tears Jakob Nielsen a new one.

I particularly like his suggestion that you re-read Nielsen’s argument but replace the word “accessibility” with “usability”:

Assessed this way, the accessibilityusabiity movement has been a miserable failure.

AccessibilityUsability is too expensive for most companies to be able to afford everything that’s needed with the current, clumsy implementation.

Products of all kinds are required to ensure misuse is discouraged, at a minimum, if not difficult or impossible. I don’t see why LLMs should be any different.

Utopia WCAG warnings | Trys Mudford

Wouldn’t it be great if all web tools gave warnings like this?

As you generate and tweak your type scale, Utopia will now warn you if any steps fail WCAG SC 1.4.4, and tell you between which viewports the problem lies.
