What about the \"aria-hidden\" attribute? Is it\'s mere p

Answer 1

You must supply a value for aria-hidden.

"If an element is only visible after some user action, authors MUST set the aria-hidden attribute to true. When the element is presented, authors MUST set the aria-hidden attribute to false or remove the attribute, indicating that the element is visible."
