Accessibility of Web Components
A great presentation on web components by Marcy, with an emphasis on keeping them accessible.

Yesterday, Aaron gave a great talk at BD Conf about forms. In one example, he was using
aria-describedby. I was a bit confused by the differences between
aria-labelledby, so Aaron has very helpfully clarified the distinction.
A great technique from Heydon for styling radio buttons however you want.
Patty’s excellent talk on responsive design and progressive enhancement. Stick around for question-and-answer session at the end, wherein I attempt to play hardball, but actually can’t conceal my admiration and the fact that I agree with every single word she said.
Léonie gives a great, clear description of how screen readers switch modes as they traverse the DOM snapshot.
Alice Bartlett shares her experience of getting aria-live regions to work in a meaningful way.
Heydon Pickering put together a great collection of accessible self-contained interface patterns that demonstrate smart use of ARIA.
Bruce’s thoughts on ensuring accessibility in Web Components. He thinks that the vocabulary of ARIA is up to the job, so that’s good enough for me.
Some sensible thoughts from Addy on how Web Components might be peer-reviewed.
A healthy dose of scepticism about Web Components, looking at them through the lenses of accessibility, security, and performance.
I share some of this concern: Web Components might look like handy ready-made out-of-the-box solutions, but the truth is that web developers have to do much more of the hard graft that was traditionally left to the browser.
Scott writes an absolutely spot-on skewering of the idea that progressive enhancement means you’re going to spend your time catering to older browsers. The opposite is true.
Progressive Enhancement frees us to focus on the costs of building features for modern browsers, without worrying much about leaving anyone out. With a strongly qualified codebase, older browser support comes nearly for free.
A love letter to HTML, prompted by the line-mode browser hack event at CERN.
A cogent definition and spirited defence of progressive enhancement:
Progressive Enhancement is an extension of our shared values on the web and goes to the root of the web. I believe—and hope you agree—that the web is for everybody and should be accessible regardless of the device a user brings to the party.
Preach it, Karen!
“Why would someone ever want to do that?” is the wrong question. It doesn’t matter why they want to do it. The fact is that people do. The right question, the one that we all should be asking, is “how can we make a better experience for them?”
Yet another timely reminder from Tim, prompted by the naysayers commenting on his previous excellent post on progressive enhancement, universal access, and the nature of the web.
A great call-to-arms from Tim, simply asking that we create websites that take advantage of the amazing universality of the web:
The web has the power to go anywhere—any network, any device, any browser. Why not take advantage of that?
Inevitably there is pushback in the comments from developers still in the “denial” stage of coming to terms with what the web is.
Carousels are shit. Auto-animating carousels are really shit. Now proven with science!
It’s great to see the changes that Facebook’s four-person accessibility team have managed to push through.
I’ll be speaking at this event in London on Thursday. It would be lovely if you could come along. It’s free!
These seem just about as reasonable as any other CAPTCHA.
This is a great initiative. I’m going to learn a lot from it. I hope that I might even be able to contribute to it sometime.
An ever-timely call-to-arms from Eric:
Sir Tim Berners-Lee envisioned the web as open and accessible for everyone, no matter where they comes from, what speed their connection is, how capable their browsers are or how good their eyes or hands or both work. I feel proud every day to make that vision reality, and it is the job of web developers to make it a reality.
He’s right. We have tremendous power and privilege, and correspondingly tremendous responsibility.
A behind-the-scenes look at how Gov.uk is handling mobile devices. Spoiler: it’s responsive.
I found this particularly interesting:
When considering the extra requirements users of different devices have we found a lot in common with work already done on accessibility.
A worrying look at how modern web developers approach accessibility. In short, they don’t.
The low-hanging fruit of accessibility fixes; it’s worth bearing these in mind.
James Craig is a mensch. This is how you give feedback to a working group.
There’s some great practical advice for building accessible mobile web apps here.
Bruce’s thoughts on the proposed inclusion of a “content” or “maincontent” element in HTML5.
Personally, I don’t think there’s much point in adding a new element when there’s an existing attribute (role=”main”) that does exactly the same thing.
Also, I don’t see much point in adding an element that can only be used once and only once in a document. However, if a “content” or “maincontent” element could be used inside any sectioning content (section, article, nav, aside), then I could see it being far more useful.
If you make inaccessible iOS apps, you really only have yourself to blame.
There are also some handy tips here for getting to know VoiceOver.
A really nice site dedicated entirely to making the web a better place for the colourblind.
Oh, this is just wonderful: a camera that outputs a text description instead of an image (complete with instructions on how to build one yourself). I love it!
A cautionary tale from Stuart. We, the makers of modern technology, are letting people down. Badly.
We’re in this to help users, remember: not just the ones who think as we do, but the ones who rely on us to build things for them because they don’t know what they’re doing. If your response is honestly “well, he should have spent more on a phone to get something better”, then I’m exceedingly disillusioned by you.
I can’t remember the last time I read something I disagreed with so fundamentally. This sums up the tone of the article:
Accessibility is not a right; it’s a feature.
I do not agree. I do not agree at all.
(Also, the pre-emtive labelling of anyone who may disagree with your point of view as defending a “sacred cow” is as tired and misguided as labelling anyone who disagrees with your viewpoint as a “fanboy”.)
Yes, yes, yes! This article does an excellent job of explaining what Captchas are attempting to do and why, therefore, they are so utterly shit.
This helps to clarify the difference between native semantics and ARIA additions.
This is a great response to my recent post about semantics in HTML. Steve explores the accessibility implications. I heartily concur with his rallying cry at the end:
Given some recent hand-wringing about the web as a “platform,” it seems appropriate to revisit this superb article from Ben. The specifics of the companies and technologies may have changed in the past year but the fundamental point remains the same:
Everything about web architecture; HTTP, HTML, CSS, is designed to serve and render content, but most importantly the web is formed where all of that content is linked together. That is what makes it amazing, and that is what defines it. This purpose and killer application of the web is not even comparable to the application frameworks of any particular operating system.
Andy responds to Joe Hewitt’s recent despondent posts about the web. I tend to agree with Andy: I think comparing the web to other “platforms” is missing the point of what the web is.

John reinforces the importance of universal access above the desire to build only for the newest shiniest devices:
Universality is a founding principle of the web. It is the manifesto the web has been built on, and I believe one of the key drivers of the almost unimaginable success of the web over these last two decades. We ignore that at the web’s peril.
A great reminder from Bruce that we need to remember to use cutting-edge web technology responsibly.
Leonie points to a change in the semantics of the a element in HTML5 that could be very handy for accessible navigation.
A cute website that’s a call-to-arms against low-contrast text on the web.

Ignoring the awful misleading title, this is a really good post from Paul on his personal experiences dealing with accessibility on one or two projects.
A superb post by Dan on the bigger picture of what’s wrong with hashbang URLs. Well written and well reasoned.
A nice succinct description of the placeholder attribute, with an emphasis on accessibility.
This consortium of institutions and universities came together “to provide practical solutions and expertise in digital preservation.”
PLANETS stands for Preservation and Long-term Access through Networked Services.
Tim Bray calmly explains why hash-bang URLs are a very bad idea.
This is what we call “tight coupling” and I thought that anyone with a Computer Science degree ought to have been taught to avoid it.
A great little jQuery script to automatically assign ARIA roles to HTML5 elements with the corresponding semantics.
Steven nails exactly why I’m so excited about the increasing diversity of devices accessing the web; not so that we can build more silos, but so that we can sure our content is robust enough for the multitude of different devices:
To be honest, I can think of a few, but not many use cases of web sites or apps which are or should be exclusively mobile. It seems like the Mobile Web allows us to revisit all of the talk of inclusion, progressive enhancement and accessibility from years ago.
