ElementInternals.ariaRoleDescription

The ariaRoleDescription property of the Element interface reflects the value of the aria-roledescription attribute, which defines a human-readable, author-localized description for the role of an element.

Note:

Setting aria attributes on ElementInternals allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the Accessibility Object Model explainer.

Syntax

ElementInternals.ariaRoleDescription = ariaRoleDescription;

Value

A DOMString.

Examples
