Axe Core 4.9

ARIA attributes must conform to valid names

The names of ARIA attributes beginning with “aria-“ must be correct.

A reference to an invalid attribute or an attribute that doesn’t exist will result in a violation of this rule.

The accessibility function intended by the developer will not be fulfilled if the developer uses an invalid or misspelled ARIA attribute.

User interface components meant to increase the accessibility and interoperability of web and application content must adhere to properly worded and up-to-date ARIA properties in order for assistive technology to provide suitable information to people with disabilities.

Insufficient usage of the WAI-ARIA 1.1 W3C Recommendation’s attributes prevents developers from correctly communicating user interface actions and structural information to assistive technology in document-level markup.

What this Accessibility Rule Checks

Verifies that all elements that contain WAI-ARIA attributes have those attributes and that they are legitimate attributes.
