Check for use of aria-hidden paired with hidden=until-found · Issue #1844 · IBMa/equal-access (original) (raw)

ARIA in HTML is updating to indicate that the use of aria-hidden=true on an element that also has the hidden=until-found attribute needs to be treated as a MUST NOT author error.

Using both together means that someone could find the hidden content using a browser in-page search, but the revealed previously hidden content will now be visually exposed, but still inaccessible to people using AT.

e.g.,

<p hidden=until-found aria-hidden=true>some content</p>
