Element aria-* Attributes Have Valid Values

Why the audit is important

Invalid ARIA attribute values may be preventing the screen reader from properly understanding the current state of a widget. This could make the page unusable to users who rely on screen readers.

See Introduction to ARIA for more information.

How to pass the audit

Below the audit, Lighthouse displays something like 1 element fails this test. The number varies depending on how many elements are failing. Click this label to expand the list. You can find each element in your DOM by running the $(), $$(), and $x() functions from the Chrome DevTools Console.

To find each listed element's invalid attribute values:

  1. Note the aria-* attributes of the element.

  2. Go to Definition of States and Properties.

  3. For each aria-* attribute of the element, go the page for that attribute.

  4. Make the value of the element's attribute match one of the supported values listed in Value.
