I Don’t Care What Google or Apple or Whomever Did | Adrian Roselli

Apple and Google get it wrong just as often as the rest of us.

Accessible HTML Elements | Amber’s Website

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.

Inclusive Inputs « Texte | ovl – code & design

This is a great walkthough of making a common form pattern accessible. No complex code here: some HTML is all that’s needed.

HTML: The Inaccessible Parts - daverupert.com

Well, this is a grim collection from Dave:

There are some cases where even using plain ol’ HTML causes accessibility problems. I get frustrated and want to quit web development whenever I read about these types of issues. Because if browsers can’t get this right, what hope is there for the rest of us.

It’s worth clicking through each link he lists—the situation is often much more nuanced than simply “Don’t use X.”

Why the GOV.UK Design System team changed the input type for numbers - Technology in government

Some solid research here. Turns out that using input type=”text” inputmode=”numeric” pattern="[0-9]*" is probably a better bet than using input type="number".

Link Targets and 3.2.5 | Adrian Roselli

Here are the many, many reasons why you should not open links in a new window (or tab).

Regardless of what accessibility conformance level you target, do not arbitrarily open links in a new window or tab. If you are required to do so anyway, inform users in text.

Standards for Writing Accessibly – A List Apart

  • Write Chronologically, Not Spatially
  • Write Left to Right, Top to Bottom
  • Don’t Use Colors and Icons Alone
  • Describe the Action, Not the Behavior

A Complete Guide to Links and Buttons | CSS-Tricks

Chris takes two side-by-side deep dives; one into the a element, the other into the button element.

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 formaction, formenctype, formmethod, formnovalidate, and formtarget?

ARIA labels | Amber’s Website

A great explanation of aria-label and aria-labelledby!

Could browsers fix more accessibility problems automatically?

Some really interesting ideas here from Hidde on how browsers could provide optional settings for users to override developers when it comes to accessibility issues like colour contrast, focus styles, and autoplaying videos.

Why `details` is Not an Accordion - daverupert.com

At the risk of being a broken record; HTML really needs <accordion> , <tabs>, <dialog>, <dropdown>, and <tooltip> elements. Not more “low-level primitives” but good ol’ fashioned, difficult-to-get-consensus-on elements.

Hear, hear!

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.

If we really want to win, let’s make it easy for everyone to access the Web.

Accessibility on The Session revisited

Earlier this year, I wrote about an accessibility issue I was having on The Session. Specifically, it was an issue with Ajax and pagination. But I managed to sort it out, and the lesson was very clear:

As is so often the case, the issue was with me trying to be too clever with ARIA, and the solution was to ease up on adding so many ARIA attributes.

Well, fast forward to the past few weeks, when I was contacted by one of the screen-reader users on The Session. There was, once again, a problem with the Ajax pagination, specifically with VoiceOver on iOS. The first page of results were read out just fine, but subsequent pages were not only never announced, the content was completely unavailable. The first page of results would’ve been included in the initial HTML, but the subsequent pages of results are injected with JavaScript (if JavaScript is available—otherwise it’s regular full-page refreshes all the way).

This pagination pattern shows up all over the site: lists of what’s new, search results, and more. I turned on VoiceOver and I was able to reproduce the problem straight away.

I started pulling apart my JavaScript looking for the problem. Was it something to do with how I was handling focus? I just couldn’t figure it out. And other parts of the site that used Ajax didn’t seem to be having the same problem. I was mystified.

Finally, I tracked down the problem, and it wasn’t in the JavaScript at all.

Wherever the pagination pattern appears, there are “previous” and “next” links, marked up with the appropriate rel="prev" and rel="next" attributes. Well, apparently past me thought it would be clever to add some ARIA attributes in there too. My thinking must’ve been something like this:

  • Those links control the area of the page with the search results.
  • That area of the page has an ID of “results”.
  • I should add aria-controls="results" to those links.

That was the problem …which is kind of weird, because VoiceOver isn’t supposed to have any support for aria-controls. Anyway, once I removed that attribute from the links, everything worked just fine.

Just as the solution last time was to remove the aria-atomic attribute on the updated area, the solution this time was to remove the aria-controls attribute on the links that trigger the update. Maybe this time I’ll learn my lesson: don’t mess with ARIA attributes you don’t understand.

A Web Developers New Working Week

I think these are great habit-forming ideas for any web designer or developer: a day without using your mouse; a day with your display set to grayscale; a day spent using a different web browser; a day with your internet connection throttled. I’m going to try these!

What I’ve learned about accessibility in SPAs

Nolan writes up what he learned making accessibiity improvements to a single page app. The two big takeways involve letting the browser do the work for you:

Here’s the best piece of accessibility advice for newbies: if something is a button, make it a <button>. If something is an input, make it an <input>. Don’t try to reinvent everything from scratch using <div>s and <span>s.

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.

Why Are Accessible Websites so Hard to Build? | CSS-Tricks

I reckon a lot of websites have bad accessibility not because folks don’t care, but because they don’t know there’s an issue in the first place.

The headline is begging the question (I don’t think accessible websites are so hard to build), but I agree with Robin’s idea:

What if our text editors caught accessibility issues and showed them to us during development?

This is something that Hidde has been talking about recently too, looking at content management systems.

Designing a focus style | Zell Liew

A deep dive info focus styles with this conclusion:

The default focus ring works. There are problems with it, but it can be good enough, especially if you can’t dedicate time and energy to create a custom focus ring.
