Subject: ARIA landmark roles and HTML 5 sectioning elements
No previous message | Next message →

With recent releases of JAWS, NVDA, and VoiceOver and recent releases of Chrome, Firefox, and Safari, is there any benefit from doubling up with code like <nav role="navigation"> or <footer role="contentinfo"> or even <form="form" >? Are there (still) some popular screen reader-browser combinations, perhaps on mobile devices, that benefit from having both HTML5 elements and also the ARIA roles? (I mean, of course, just in those cases where you do have equivalence.) Is there a downside to doubling up?
Thanks,
Alan

The first rule of ARIA is only use ARIA when you can't do something via HTML.

Of course, the "rule" is essentially a best practice recommendation. And
this answer bypasses the actual question: is explicitly adding the same
ARIA role that the element has natively anyway a problem or not? It was
done in the past for some user agents that didn't have the correct
native role assignment (for instance, IE11 not recognising <main>
element, so needed an extra helping hand with <main role="main">).

More recently, Safari/VO still has a problem where an <img> with an SVG
source is not exposed as an actual image, which can be remediated with
an arguably redundant role="img".

In answer to the original question, I'd say: it's probably more a case
of "it's pointless/redundant to do it nowadays" (depending on which
browsers you're targetting ... if you are still seeing/expecting traffic
from a lot of *really* old browsers, then it may well be necessary).
But it doesn't do any harm per se.

What patrick said!

This used to be recommended particularly for IE compatibility, so
you'll probably continue to see this in the wild for some time.
