The accessible name is the name of a user interface element. The Accessible Name Computation spec provides a calculation of an accessible NAME. If the role is a static role then aria-label will be ignored by all screen readers except Talkback which overrides the static content (except if its listitem role, then its ignored).JAWS ignores the aria-label or aria-labelledby. If its a heading role, aria-label or aria-labelledby overrides it on NVDA, VoiceOver and Talkback.If the role is an interactive role (that can be clicked on such as button or link) or an image role the aria-label or aria-labelledby overrides the text.VO on iOS only reads it if on landmark roles.Īria-label and aria-labelledby have similar behaviour in screen readers and the Accessibility API, but aria-label should be reserved for when there is no visible text on the page to reference or when keeping track of id values would be too difficult. VO on MacOS is OK on most static content. Ignored on static content not listed above unless given an interactive role and tabindex=0, and then only if the users tabs to it (not arrows to it). H1, h2, h3, h4, h5, h6 are OK as are elements with role=heading. Other elements read aria-label with virtual cursor and then let user enter and read the contents.Īll the static content is overridden except ul and li which are ignored

All three are OK on nav and main elements.

By design, aria-label or aria-labelledby replace any other label text inside the element. They also work well on div and span elements with interactive roles such as role=link, button.

aria-label, aria-labelledby and aria-describedby are robustly supported for interactive content elements such as links and form controls including the many input types.

Screen readers are all over the map on what they do when an aria-label, aria-labelledby, and aria-describedby on static content Results Well supported elements This is what is below, along with aria-labelledby and aria-describedby, as well as an examination of what is "supposed to happen" according to the Accessible Name computation. I was asked to test the results of aria-label on static content. What happens with aria-labelledby, aria-label and aria-describedbyĪn interesting Twitter thread sprung up from a Tweet about overriding elements with aria-label with a follow up thread with my colleagues.
