Elements must only use supported ARIA attributes
What is the problem?
The aria-allowed-attr rule ensures that ARIA attributes are used correctly on HTML elements. This means that the ARIA attributes should be compatible with the role of the element they are applied to.
Impacted Groups
Why is this important?
Using ARIA attributes incorrectly can confuse assistive technologies like screen readers. This can lead to incorrect information being conveyed to users, making it harder for them to understand and interact with the content.
How to solve this issue
To fix this, use ARIA attributes that are compatible with the element's role. Consult the ARIA specification for detailed information on how to use ARIA attributes correctly.
