ARIA roles used must conform to valid values
Log in (Premium content) Request a demo
Values assigned to ARIA roles (
role="") must be valid. This means values must be spelled correctly, must correspond to existing ARIA
role values, and must not be abstract roles in order to correctly expose the purpose of the element.
The Algorithm, in Simple Terms
Checks all elements that contain the WAI-ARIA role attribute to ensure that the role value is valid
Why this is Important
If an ARIA role is assigned an invalid value, the role will not be able to perform the accessibility function intended by the developer.
How to Fix the Problem
Ensure all values assigned to
role="" correspond to valid ARIA roles.
