An excellent collection of advice and examples for making websites responsive and accessibile (responsive + accessible = responsible).
We often have brown bag lunchtime presentations at Clearleft. In the Before Times, this would involve a trip to Pret or Itsu to get a lunch order in, which we would then proceed to eat in front of whoever was giving the presentation. Often it’s someone from Clearleft demoing something or playing back a project, but whenever possible we’d rope in other people to swing by and share what they’re up to.
We’ve continued this tradition since making the switch to working remotely. Now the brown bag presentations happen over Zoom. This has two advantages. Firstly, if you don’t want the presenter watching you eat your lunch, you can switch your camera off. Secondly, because the presenter doesn’t have to be in Brighton, there’s no geographical limit on who could present.
Our most recent brown bag was truly excellent. I asked Léonie if she’d be up for it, and she very kindly agreed. As well as giving us a whirlwind tour of how assistive technology works on the web, she then invited us to observe her interacting with websites using a screen reader.
I’ve seen Léonie do this before and it’s always struck me as a very open and vulnerable thing to do. Think about it: the audience has more information than the presenter. We can see the website at the same time as we’re listening to Léonie and her screen reader.
We got to nominate which websites to visit. One of them—a client’s current site that we haven’t yet redesigned—was a textbook example of how important form controls are. There was a form where almost everything was hunky-dory: form fields, labels, it was all fine. But one of the inputs was a combo box. Instead of using a native
select with a
And that’s why you use the right HTML element wherever possible, kids!
The other site Léonie visited was Clearleft’s own. That was all fine. Léonie demonstrated how she’d form a mental model of a page by getting the screen reader to read out the headings. Interestingly, the nesting of headings on the Clearleft site is technically wrong—there’s a jump from an
h1 to an
h3—probably a result of the component-driven architecture where you don’t quite know where in the page a heading will appear. But this didn’t seem to be an issue. The fact that headings are being used at all was the more important fact. As Léonie said, there’s a lot of incorrect HTML out there so it’s no wonder that screen readers aren’t necessarily sticklers for nesting.
I’ve said it before and I’ll say it again: if you’re using headings, labelling form fields, and providing alternative text for images, you’re already doing a better job than most websites.
Headings weren’t the only way that Léonie got a feel for the page architecture. Landmark roles—like
nav—really helped too. Inside the
nav element, she also heard how many items there were. That’s because the navigation was marked up as a list: “List: six items.”
And that reminded me of the Webkit issue. On Webkit browsers like Safari, the list on the Clearleft site would not be announced as a list. That’s because the lists’s bullets have been removed using CSS.
Now this isn’t the only time that screen readers pay attention to styling. If you use
display: none to hide an element from sight, it will also be unavailable to screen reader users. Makes sense. But removing the semantic meaning of lists based on CSS? That seems a bit much.
There are good reasons for it though. Here’s a thread from James Craig on where this decision came from (James, by the way, is an absolute unsung hero of accessibility). It turns out that developers went overboard with lists a while back and that’s why we can’t have nice things. In over-compensating from divitis, developers ended up creating listitis, marking up anything vaguely list-like as an unordered list with styling adjusted. That was very annoying for screen reader users trying to figure out what was actually a list.
And James also asks:
If a sighted user doesn’t need to know it’s a list, why would a screen reader user need to know or want to know? Stated another way, if the visible list markers (bullets, image markers, etc.) are deemed by the designers to be visually burdensome or redundant for sighted users, why burden screen reader users with those semantics?
That’s a fair point, but the thing is …bullets maketh not the list. There are many ways of styling something that is genuinely a list that doesn’t involve bullets or image markers. White space, borders, keylines—these can all indicate visually that something is a list of items.
If you look at, say, the tunes page on The Session, you can see that there are numerous lists—newest tunes, latest comments, etc. In this case, as a sighted visitor, you would be at an advantage over a screen reader user in that you can, at a glance, see that there’s a list of five items here, a list of ten items there.
So I’m not disagreeing with the thinking behind the Webkit decision, but I do think the heuristics probably aren’t going to be quite good enough to make the call on whether something is truly a list or not.
Still, while I used to be kind of upset about the Webkit behaviour, I’ve become more equanimous about it over time. There are two reasons for this.
Firstly, there’s something that Eric said:
We have come so far to agree that websites don’t need to look the same in every browser mostly due to bugs in their rendering engines or preferences of the user.
I think the same is true for screen readers and other assistive technology: Websites don’t need to sound the same in every screen reader.
That’s a really good point. If we agree that “pixel perfection” isn’t attainable—or desirable—in a fluid, user-centred medium like the web, why demand the aural equivalent?
The second reason why I’m not storming the barricades about this is something that James said:
Of course, heuristics are imperfect, so authors have the ability to explicitly override the heuristically determined role by adding
That means more work for me as a developer, and that’s …absolutely fine. If I can take something that might be a problem for a user, and turn into something that’s a problem for me, I’ll choose to make it my problem every time.
I don’t have to petition Webkit to change their stance or update their heuristics. If I feel strongly that a list styled without bullets should still be announced as a list, I can specificy that in the markup.
It does feel very redundant to write
ul role="list”. The whole point of having HTML elements with built-in semantics is that you don’t need to add any ARIA roles. But we did it for a while when new structural elements were introduced in HTML5—
nav role="navigation", etc. So I’m okay with a little bit of redundancy. I think the important thing is that you really stop and think about whether something should be announced as a list or not, regardless of styling. There isn’t a one-size-fits-all answer (hence why it’s nigh-on impossible to get the heuristics right). Each list needs to be marked up on a case-by-case basis.
And I wouldn’t advise spending too much time thinking about this either. There are other, more important areas to consider. Like I said, headings, forms, and images really matter. I’d prioritise those elements above thinking about lists. And it’s worth pointing out that Webkit doesn’t remove all semantic meaning from styled lists—it updates the
role value from
group. That seems sensible to me.
In the case of that page on The Session, I don’t think I’m guilty of listitis. Yes, there are seven lists on that page (two for navigation, five for content) but I’m reasonably confident that they all look like lists even without bullets or markers. So I’ve added
role="list" to some
As with so many things related to accessibility—and the web in general—this is a situation where the only answer I can confidentally come up with is …it depends.
You’re not going to get a Webby Award or thousands of views on Codepen for how amazingly crafted your HTML is. You’ll need to be OK going unrecognized for your work. But know that every time I use a screen reader or keyboard on a site and it works correctly, I have a little spark of joy.

A really great one-page guide to HTML from Bruce. I like his performance-focused intro:
If your site is based on good HTML, it will load fast. Browsers incrementally render HTML—that is, they will display a partially downloaded web page to the user while the browser awaits the remaining files from the server.
This is a terrific explanation of the concept of accessible names in HTML, written with verve and style!
Contrary to what you may think, naming an element involves neither a birth certificate nor the HTML
nameattribute is never directly exposed to the user, and is used only when submitting forms. Birth certificates have thus far been ignored by spec authors as a potential method for naming controls, but perhaps when web UI becomes sentient and self-propagating, we’ll need to revisit that.
Consider what React and other SPA frameworks are good for: stateful, extensible component-driven applications. Now consider what a résumé’s goals are.
This surprises me. But forewarned is forearmed.
Amber runs through some HTML elements that help you provide semantic information—and accessibility—for your website: headings, paragraphs, lists, and more:
You may be aware that ARIA roles are often used with HTML elements. I haven’t written about them here, as it’s good to see how HTML written without ARIA can still be accessible.
Like a little mini CSS Zen Garden, here’s one compenent styled five very different ways.
Crucially, the order of the markup doesn’t consider the appearance—it’s concerned purely with what makes sense semantically. And now with CSS grid, elements can be rearranged regardless of source order.
CSS is powerful and capable of doing amazingly beautiful things. Let’s embrace that and keep the HTML semantical instead of adapting it to the need of the next design change.
Chris takes two side-by-side deep dives; one into the

Even if you think you already know those elements well, I bet there’ll be something new here for you. Like, did you know that the
button element can have form over-riding attributes like
It’s now easier than ever to style form controls without sacrificing semantics and accessibility:
The reason is that we can finally style the ::before and ::after pseudo-elements on the
<input>tag itself. This means we can keep and style an
<input>and won’t need any extra elements. Before, we had to rely on the likes of an extra
<span>, to pull off a custom design.
The demo is really nice. And best of all, you can wrap all of these CSS enhancements in a feaure query:
Hopefully, you’re seeing how nice it is to create custom form styles these days. It requires less markup, thanks to pseudo-elements that are directly on form inputs. It requires less fancy style switching, thanks to custom properties. And it has pretty darn good browser support, thanks to
At the risk of being a broken record; HTML really needs
<tooltip>elements. Not more “low-level primitives” but good ol’ fashioned, difficult-to-get-consensus-on elements.
I wish browsers would prioritize accessibility improvements over things like main thread scheduling optimization to unblock tracking pixels and the Sisyphean task of competing with native.

And then there are all the issues that crop up when you take over the task of handling navigations:
- You need to manage focus yourself.
- You need to manage scroll position yourself.
For classic server-rendered pages, most browser engines give you this functionality for free. You don’t have to code anything. But in an SPA, since you’re overriding the normal navigation behavior, you have to handle the focus yourself.
Six steps that everyone can do to catch accessibility gotchas:
- Check image descriptions
- Disable all styles
- Validate HTML
- Check the document outline
- Grayscale mode
- Use the keyboard
