Definition
The accessibility tree is the browser’s simplified structure of a page for assistive technologies, exposing roles, names, and states derived from HTML and ARIA.
Real-World Example
Screen readers navigate the accessibility tree, so a button needs an accessible name — visible text or aria-label — to be understandable.
