Rule Description

Certain ARIA roles must be contained by particular parent roles in order to perform the intended accessibility functions.

The Algorithm, in Simple Terms

Checks all elements that contain a WAI-ARIA role to ensure that all required parent roles are present

Why this is Important

For each role, WAI-ARIA explicitly defines which child and parent roles are allowable and/or required. ARIA roles missing required parent roles will not be able to perform the accessibility functions intended by the developer.

How to Fix the Problem

Ensure all ARIA roles are contained by their required parent element, if any.
