Accessibility

ARIA attributes must conform to valid names

ARIA attributes should adhere to valid names to ensure compatibility, interoperability, and compliance with accessibility standards, promoting consistency and effective web content accessibility

If the developer uses a non-existent or misspelled ARIA attribute, the attribute will not be able to perform the accessibility function intended by the developer.

In order to allow assistive technologies to convey appropriate information to persons with disabilities, user interface elements intended to improve the accessibility and interoperability of web and application content must conform to properly spelled and current ARIA attributes.

When developers do not use attributes defined in the WAI-ARIA 1.1 W3C Recommendation, they do not properly convey user interface behaviors and structural information to assistive technologies in document-level markup.

Fixing the problem

This rule checks for the presence of an unrecognized ARIA attribute, which prevents the attribute from functioning as intended.

Ensure all ARIA attributes (as opposed to the values inside of them) used are spelled correctly and correspond to valid ARIA attribute names.

For example, aria-hidden="true" would pass, while aria-visible="rute" would fail.

Authoring Tools: Using authoring and debugging tools that compare attributes for widget roles, states, and properties to those supported in WAI-ARIA may check the validity of ARIA attributes automatically during development, but they cannot reliably eliminate the need for testing.
