WAI-ARIA APG Tooltip Pattern
Defines tooltips as focus or hover-triggered information popups, with focus remaining on the trigger, Escape dismissal, blur dismissal, pointer-out dismissal, and open-while-hovering behavior.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Tooltip | Choose tooltip when the target already has a usable name and needs only a short supplemental description on focus or hover. | The owning element keeps focus while the tooltip is visible. | Supports focus and hover triggering, focus staying on the trigger, and Escape dismissal behavior. |
| Tooltip-only required information | Flag this anti-pattern when the tooltip content is necessary to complete the task correctly or avoid a harmful outcome. | Users can complete the task without reading a tooltip. | Supports the tooltip interaction contract where focus remains on the trigger and the popup is dismissed by Escape, blur, or pointer out. |
