Should I use aria hidden?

Use caution when using aria-hidden to hide visibly rendered content from assistive technologies. You should not be hiding visible content unless doing so improves the experience for users of assistive technologies by removing redundant or extraneous content.

How do I hide my aria-label?

To hide an element to screen readers (and child elements), simply add the aria-hidden="true" attribute. Content can still be made accessible to ATs via aria-describedby or aria-labelledby .

Does aria hidden apply to child elements?

In some browsers, the attribute aria-hidden="true" hides an element and all its children from assistive technologies. Users can still use the keyboard to navigate to any focusable child elements, but their content is inaccessible to people who use assistive technologies. For example, screen readers are silent.

What is the difference between the following attributes hidden aria hidden true and role presentation or role None?

While aria-hidden=true can be used to hide an element and its descendant content from assistive technologies, the none and presentation roles are to be used to only suppress the implicit ARIA semantics of an element. These roles do not hide the element's content from assistive technologies.
