If you click on the text inside the summary element (which defaults to the text “details” if absent), the details element expands. Click again, and it contracts.
The answer is because it’s much more hassle to pull in script and keep role and state info with ARIA. It’s much better to build these things into the language, with built-in accessibility because the browser vendors bake in role and state information and hook up the widgets to the operating system.
Expecting developers to reinvent this wheel every time is “bolt-on” accessibility, and we all know that they won’t actually do it. Yes, they can use a library. I’ve seen the whole jQuery library pulled in just to make an expando box behave like details.
I refer you to John Foliot, whose email to the HTML Working Group makes an excellent argument that explains the subject much better than I can. I should add that Foliot is by no means an HTML5 cheerleader and is a great advocate of accessibility and ARIA. His main points are
If something needs to be referenced you should normally make it an element, with an id attribute
If something represents a separate entity, make it an element: you might want to add attributes later
having a simple element express something instead of requiring a bunch of lines of scripting is way more efficient.
moving functionality into the browser natively, instead of relying on scripting which requires additional CPU is an efficient design choice
having ‘accessibility’ built-in rather than bolt-on (which is what ARIA is) is a fundamental desire of most of us in the a11y community.
I agree. It is. It’s also several different kind of messes, not all of which are avoidable or bad. Let’s look at them.
The backwards compatibility mess
The first kind of mess is because it builds on HTML 4. I’m sure if you were building a mark-up language from scratch you would include elements like footer, header and nav (actually, HTML 2 had a menu element for navigation that was deprecated in 4.01).
You probably wouldn’t have loads of computer science oriented elements like kbd,var, samp in preference to the structural elements that people “fake” with classes. Things like tabindex wouldn’t be there, as we all know that if you use properly structured code you don’t need to change the tab order, and accesskey wouldn’t make it because it’s undiscoverable to a user and may conflict with assistive technology. Accessibility would have been part of the design rather than bolted on.
But we know that now; we didn’t know that then. And HTML 5 aims to be compatible with legacy browsers and legacy pages. This page is written in HTML 5, and although your browser doesn’t “understand” it, it it still renders it.
There was a cartoon in the ancient satirical magazine Punch showing a city slicker asking an old rural gentleman for directions to his destination. The rustic says “To get there, I wouldn’t start from here”. That’s where we are with HTML. If we were designing a spec from scratch, it would look much like XHTML 2, which I described elsewhere as “a beautiful specification of philosophical purity that had absolutely no resemblance to the real world”, and which was aborted by the W3C last week.
That’s one reason why HTML 5 a mess. It’s built on a mess.
Why is the nav element so loosely specified? (“Only sections that consist of major navigation blocks are appropriate for the nav element”—define “major”, if you please.) Why can you have nav inside a header and not in a footer?
I should clarify two things after some tweets and a Skype conversation with Lachlan Hunt. The first is in fairness to Hixie: he changed the definition of nav to clarify that there can be more than one per page, and I agreed that the new defintion was an improvement. But, as I’m a self-confessed dimwit, I only realised later that the word “major” leaves ambiguity as well. So that’s my brain parsing slowly, not Hixie’s bad.
Secondly, and most importantly, I haven’t had some kind of damascene conversion to the anti-HTML 5 camp. I firmly believe that it’s the best way forward for an Open Standard that allows us to write richer web pages and applications. And I’m sure that no-one, especially those in the Working Group, believes it’s perfect already. In fact, the Working Group consistently call for developer participation in reviewing the spec.
To reiterate: bitching in blogs (like I’m doing now!) and on twitter is OK, but the best way to be sure that your views are heard is to mail to Working Group.
An Event Apart Boston is going swimmingly, but I’m taking a break to post this story from a BBC site that explains that the BBC has taken the decision to remove the hCalendar microformat from /programmes until
either the BBC accessibility group does further testing and declares the abbreviation design pattern to be safe to use
or the microformats community settles on an accessible alternative to the abbreviation design pattern
I’ve long been worried about the accessibility of microformats, so experimented and found that the way that dates are marked up is inaccessible to users of the big two screenreaders, and began writing an article to that effect.
James Craig, who is 97 times more helpful than I am, decided to research a better way to embed machine-parsable dates in content.
We jointly wrote up our results in an article called “hAccessibility“, which James published today.
Yay for the Geek in the Park meeting. I missed the picnic, as I was returning from monstrous partying for my kid brother’s birthday, but got there in time to actually have a pre-speaking run-through with my partner-in-crime, Pat Lauke, to make sure the two-handed presentation we’d jammed by phone and mail worked.
My notes, combined with some notes Patrick gave me, are reproduced. These are dense, as we talked for two hours, as this is just our crib sheet rather than a full transcript (if you want the full thing, we are available for weddings, barmitzvahs and satanic orgies. Especially satantic orgies).
In the world of religious loonies, there are two main kinds of nutter. One is the fundamentalist – someone with the attitude that a tract is the work of God, perfect and unquestionable; if it’s mentioned in the Book, it’s beyond doubt no matter how daft. The second sub-genre of nutter is the exegesist: someone who believes that extra, unwritten information may be teased out of the text with enough insight and critical reading.
Web Standards evangelist types will all recognise both type of adherent to that Holy of Holies: the w3c specs.
Sun 18 Sept, 8.30 p.m. This post is already marked “considered harmful” as the script does not give maximum accessibility, nor fill the browser with nourishing valid code. The comments are good, though: thanks Gez and Lachlan. A proper script will appear in a couple of days, so watch this space. (Hey, does that mean I’m a script-tease artist?). There’s also a good discussion of the subject on the Accessify forum.
