ARIA expanded

What It Means

An aria-expanded attribute is present.

Why It Matters

The aria-expanded attribute indicates the status of content that can be expanded and collapsed.

What To Do

Ensure that aria-expanded is used correctly (typically on a button that controls expandable content) and that the value (true or false) reflects the expansion state.

The Algorithm... in English

An element with an aria-expanded attribute is present.
