aria-description

String

Supplies a plain-text description of an element directly, as an alternative to aria-describedby when the text doesn't already exist on the page. Screen readers announce it as supplementary detail after the name and role. Support is still emerging, so back it up with a more established technique where the description is essential.

aria-description="…"

Value

Any string of text.

Used on

Any HTML element — aria-description is a global property.

Associated roles

Every ARIA role. As a global property, aria-description is supported on all roles.

Example

aria-description="…"

<button aria-description="Opens in a new tab">Docs</button>
