Use this checklist to prepare testing and review common risk areas. It is a working aid, not a substitute for a complete accessibility audit.
Structure and navigation
- Page has one descriptive H1.
- Headings describe sections and do not skip levels for visual styling alone.
- Landmarks identify header, navigation, main content and footer.
- Skip link appears on focus and moves to main content.
- Link text identifies the destination without relying only on surrounding text.
Keyboard and focus
- All interactive controls are reachable by keyboard.
- Focus order follows the visual and logical order.
- Focus indicators are visible and not obscured.
- Dialogs move focus inside on open and return focus on close.
- Escape or another documented mechanism closes dismissible overlays.
Forms and errors
- Every input has a visible label.
- Required fields are communicated in text.
- Instructions are associated programmatically.
- Error summary appears before the form after failed submission.
- Inline errors identify the field and the required correction.
Content, media and responsive behavior
- Images have useful alternative text or are properly decorative.
- Captions or transcripts are provided where needed.
- Text reflows at 320 CSS pixels without horizontal scrolling.
- Text spacing changes do not hide content.
- Touch targets are large enough and not crowded.
Verification notes
Record the page, component, state, browser, assistive technology and date for each issue. Keep evidence specific enough for another person to reproduce.
