Create accessible tooltips

Inaccessible tooltips leave keyboard and screen reader users without important contextual information, creating an unequal experience and potential confusion.

Quick Reference

• Tooltips must be keyboard accessible (focusable trigger)
• Use aria-describedby to associate tooltip with trigger
• Allow hover and focus to show tooltip, Escape to dismiss
• Ensure sufficient contrast and don't hide essential info in tooltips

Check

Verify tooltips are keyboard accessible, use appropriate ARIA roles (tooltip), and can be dismissed without moving focus.

Fix

Implement tooltips with role='tooltip', aria-describedby, keyboard triggering, and Escape key dismissal.

Explain

Explain the accessibility requirements for tooltips including keyboard access, ARIA attributes, and timing considerations.
