css aria

Can you use the control with touch gestures?

First, you need to understand how to use the roles, including getting the nesting right. Adding an ARIA role overrides the native role semantics in the accessibility tree which is reported via the accessibility API, and therefore ARIA indirectly affects what is reported to a screen reader or other assistive technology.

For Safari + VoiceOver on iOS specifically, this does incorrectly announce table semantics in the form of, “Table start…” and “Table end…”. This should not make it harder / impossible to make responsive tables. For most part safari does help, however when it does not work – it does not work and frustrates me to hell. section obviously it had to be responsive so I picked a template that worked pretty well for styling part. Development teams will appreciate the advantage of terse code that’s easier to maintain. My suggestion above is an effort to simplify the heuristics that browsers use to decide what is and isn’t a data table. Why should the browser/AT incapability to distinguish the semantically wrong HTML layout and the semantically correct DOM with some visual-only tweaks for minor layout enhancement be the problem of web devs who consciously use HTML to express semantics and CSS just to present it nicely in certain circumstances, not of the developers of these browsers/AT who should improve their heuristics to match the web devs intentions better? The table role should be added to the

element. The aria-current attribute is intended to solve this problem. Since much of the rest of your response is predicated on one or both of those being yes, I’ll just tackle specific points you make. Maybe weigh in on the discussion [Proposal] new attribute for specifying focus and reading order at WICG Discourse. If the visual design constraints rule out the use of a particular native element, because the element cannot be styled as required.

Only put it on the body element if your page consists solely of a widget or set of widgets that all need the focus mode to be turned on.

Importantly, aria-labelledby overrides all other name sources for an element. But what we can be sure of, in these cases, is that it is not the fault of the screen reader.

The aria-controls attribute creates a cause and effect relationship. This document is a practical guide for developers on how to add accessibility information to HTML elements using the Accessible Rich Internet Applications specification [WAI-ARIA-1.1], which defines a way to make Web content and Web applications more accessible to people with disabilities. It now has the ARIA roles I outlined above, and it does not add the replacement text for the row headers until you click the button. The re-ordering issue is easy to solve — don’t use CSS to re-order table content. Under what circumstances may this not be possible?

The button is only there to give you a chance to experience the table without the replacement text (in a narrow view). If anything, the spec is the result of those earlier coders.

Not unique to flex.

Refer to the Document conformance requirements for use of ARIA attributes in HTML table in the ARIA in HTML specification. No.

It uses the same code as my responsive accessible table, but with two differences. If the content and interaction is only supported in a scripting-enabled browsing context, i.e. Based on the keyboard shortcuts defined in the AOL DHTML Style guide for tooltip. It's almost always best to use the native inputs for these.

I made videos with a screen reader to try to demonstrate how you can ruin the ability to navigate and parse a table just by adding flex. It is inappropriate to cite this document as other than work in progress.

I doubt that there are many, not used to screenreaders, could understand anything in that speed. This is not supported on devices which only provide a touch screen, and has limited or no support (depending on the specific operating system) on mobile phones/tablets with an additional physical keyboard. Well it was an idea.

In general these can be simple. Recommended to use Flexbox instead for layout.

I am not feeling comfortable with the redundancy of calling it tr and role both where it can be inferred.

Or do you suggest that changing the semantics of the element by just changing its styling is OK? I hope this second Firefox bug will be resolved at some point, as well as similar bugs for other browsers (if they are not filed yet, they should be). disclosures, Making Non accessible Elements Accessible, Accessible Name and Description: Computation and, Document conformance requirements for use of, https://www.w3.org/TR/wai-aria-practices-1.1/, Can you get to the control via the keyboard? If such a box is a grid item, it is blockified first, and so anonymous box creation will not happen.

But I’m still a bit confused about the first statement: doesn’t it turn out that display:table/table-cell does affect the semantics of the ‹div› element (at least in Chrome)? Thank you for using my tool. That will force municipalities to fix their roads. The following example of aria-labelledby with multiple references uses a span with a tabindex=-1 added.

Of course, we need some stats first, how much existing content relies on that “magic” — but I hope it’s not really that much of it. I guess we should gather stats of how these features are really used and what web devs are meaning by them, collect the feedback of actual ATs users which behavior is helpful for them and which is not, and file bugs to browsers and ATs if necessary — as it seemed to work in Firefox case above….

Check the Chrome accessibility inspector. One is an example of one of my responsive tables with ARIA added, and the other is the Twitter conversation that started this along with some generalized responses.

We are supposed to make things work for our users and file bugs when the specs and browsers get it wrong. Keep reading for how to use the buttons to the left.

Just to give more context on a sample issue I am currently struggling. For further information on the use of role=application refer to If you use the WAI-ARIA role "application", please do so wisely! trademark and Aren’t these statements kind of contradicting each other? Keyboard Support. In Internet Explorer, if you use aria-labelledby with multiple id references or aria-describedby with single or multiple id references, the referenced elements must be what Microsoft terms as accessible HTML elements. Add the error text as child of the referenced element in the DOM when the error state occurs. For me, it’s kind of false dichotomy: what car users really want is probably to drive in the cars with good shocks on the roads with no potholes:). with, Applying ARIA roles to retain table semantics can be problematic for responsive tables where header cells or other cells are discarded, a common pattern in responsive table examples. Based on that, my read is that browsers dumping table semantics is a bug. You may want to make that stand out. If you find you want to use CSS flex, grid, block, inline, or other display properties on a table, then maybe consider what the heck you are doing with the table. The closest statement about interaction with tables that I can find in the Flexbox specification is a note directed at user agent makers, and says nothing about changing the semantics: Note: Some values of display normally trigger the creation of anonymous boxes around the original box. I cannot understand anything. Just checked Steve’s test case in the accessibility tree and in NVDA and it looks fixed indeed, for display:block.

If the ARIA role or aria-* attribute does not rely on scripting to provide interaction behaviour, then it is safe to include the ARIA markup inline.

Do not change native semantics, unless you really have to. Chrome 80 no longer drops semantics for HTML tables when the display properties flex, grid, inline-block, or contents are used. accessibility, ARIA, css, html, standards, tables, usability, UX, More recent post: CSUN 2018: Everything I Know About Accessibility I Learned from Stack Overflow, The videos would be a better demonstration if anyone not used to a screenreader would understand them. Even then, find someone knowledgeable who can actually test two versions of this: One with and one without role=application set to see which model works best.

CSS 2.x also accounts for non-HTML pages, where it adds the semantics and generates the necessary anonymous table objects around itself: In other document languages (such as XML applications), But it can still be pressed, it is still in the default tab order, still looks like a button and still triggers any associated actions when pressed. This document provides advice for use of ARIA attributes in [HTML51].
