![]() ![]() For elements with no required children, any elements nested inside the element with role="presentation" or role="none" preserve their semantics. If we had nested a list within one of those 's, they would be visible to assistive technologies. While the elements, in this case, are not exposed to assistive technologies, descendants of those required elements are exposed. This is because ARIA requires the listitem elements to have a parent list element. But, elements inside of the and elements, including nested tables, are exposed to assistive technologies.īecause the presentation role was applied to the element, every child element inherits the presentation role. If presentation or none is applied to a element, the descendant, ,, ,, , and elements inherit the role and are thus not exposed to assistive technologies. When an element has required descendants, such as the various, elements and s children of a or, the presentation or none role on the table or list removes the default semantics of the element on which it was applied and their required descendant elements. The heading role semantics are removed, but the content itself is still available. Writing Democracy Dies in Darkness removes the heading semantics of the element, making it the equivalent of Democracy Dies in Darkness. This is done with the presentation role or its synonym role none, which declare that an element is being used only for presentation and therefore does not have any accessibility semantics. While ARIA is primarily used to express semantics, there are some situations where hiding an element's semantics from assistive technologies is helpful. ![]()
