aria-valid-attr

ARIA attributes need to adhere to valid names.

Severity: Critical

Description

ARIA properties starting with aria- should have valid names.

Why is it important?

When an element with an invalid ARIA attribute name is encountered, an assistive technology may disregard the element or react to it unexpectedly. As a consequence, individuals who use assistive technologies may find it challenging or impossible to use the element. Consult the official WAI-ARIA specification provided by the W3C (World Wide Web Consortium) to identify and understand the correct usage of ARIA attributes.

How to fix?

Provide a valid name for each ARIA attribute:

  • Ensure the correct attribute name is used.
  • Ensure the attribute name is spelled correctly.
