RE: How important is aria-hidden, when already hidden with CSS?

I’d recommend not using aria-hidden if you are already using display:none, for the same reason that you should not use role=link on a link, or role=button on a button, because all are already accessible and natively supported by ATs without these.

Subject: How important is aria-hidden, when already hidden with CSS?

 

I have content with CSS display:none; visibility:hidden. The WAI-ARIA spec says add aria-hidden, to ensure support support for assistive technologies (AT) that access the DOM directly.

 

For practical accessibility: which AT accesses the DOM directly?

 

For conformance: is the CSS alone enough to meet WCAG success criteria?
