Elements must only use permitted ARIA attributes

Serious

What is the problem?

The aria-prohibited-attr rule ensures that ARIA attributes are used correctly and only on elements that support them. Using prohibited ARIA attributes can confuse assistive technologies and lead to unexpected behavior.

Why is this important?

Incorrectly using ARIA attributes can make web content difficult or impossible to access for people who rely on assistive technologies, such as screen readers. This can limit their ability to use the website and access the information they need.

How to solve this issue

To fix this issue, consult the ARIA specification to determine which ARIA attributes are allowed for each HTML element. Use only valid ARIA attributes and ensure they are used correctly. By following these guidelines, you can ensure that your website is accessible to all users.
