What we test
- Semantic structure, headings, landmarks, labels, names, roles, values, and status messages.
- Keyboard-only navigation, visible focus, focus order, no keyboard traps, skip links, and focus that is not hidden.
- Text and non-text contrast, zoom, reflow, spacing, orientation, and color-independent meaning.
- Touch target size, pointer cancellation, dragging alternatives, and motion controls.
- Reduced motion, pause and stop controls, flashing limits, and nonessential animation.
