Accessibility Checking for Large Sites

Rocket Validator integrates axe-core version 4.6, into an automated web site scanner.

Valid values must be present for ARIA properties that begin with aria-.

To fulfill the intended accessibility purpose, these values must be written correctly and relate to values that make sense for a certain property.

ARIA attributes (those beginning with aria-) must have legitimate values. For a given attribute to fulfill the intended accessibility function, these values must be written correctly and correlate to values that make sense.

A diverse range of values are accepted for many ARIA attributes. There must be permitted values, acceptable “undefined” values, and acceptable “default” values.

Content that does not adhere to the permitted values is inaccessible to users of assistive technology.
