aria-roles

Description

ARIA roles assigned to an element using the role attribute must be a valid one. If any element is assigned to an invalid ARIA role, screen readers and other assistive technologies can’t identify it. This makes the webpage inaccessible to users of such technologies.

Incorrect definitions of ARIA roles usually happen due to spelling mistakes and usage of invalid ARIA roles.

Example

In the following example, the role navigationmenu is an invalid ARIA role. Screen readers and other assistive technologies can’t identify what it means. This makes the code snippet inaccessible. It breaks the aria-roles rule.

In contrast, the following code snippet correctly uses the navigation role. Hence, this code snippet is accessible and doesn’t break the aria-roles rule.

How to fix?

You can follow these steps to fix issues if this rule gets flagged:

• Check if you have defined invalid values for the role attribute.
• If so, use the correct value to fix the issue.
