aria-tooltip-name

ARIA tooltip should be assigned an accessible name.

Description

An ARIA tooltip is a contextual popup that provides descriptive text for an interface element. Normally, the tooltip appears when the mouse is placed over the element or when the element receives focus. For screen reader users, it is essential that ARIA tooltip elements have clear and descriptive text that accurately conveys the purpose, function, action, or destination they represent.

Why is it important?

The accessible name serves the purpose of providing context to users of assistive technologies, allowing them to identify and understand certain elements. If an ARIA tooltip does not have an accessible name, individuals who rely on assistive technologies are unable to determine its purpose.

How to fix?

Ensure that each element with role="tooltip" has an accessible name using one of the following -

• An aria-labelledby attribute that references elements that are visible to screen readers.
• title attribute that is not empty.
• aria-label attribute that is not empty.
