Fix accessibility issues.
how to use
Do not rewrite large parts of the UI. Prefer minimal, targeted fixes.
when to apply
Reference these guidelines when:
- adding or changing buttons, links, inputs, menus, dialogs, tabs, dropdowns
- building forms, validation, error states, helper text
- implementing keyboard shortcuts or custom interactions
- working on focus states, focus trapping, or modal behavior
- rendering icon-only controls
- adding hover-only interactions or hidden content
rule categories by priority
| priority | category | impact |
|---|
| 1 | accessible names | critical |
| 2 | keyboard access | critical |
| 3 | focus and dialogs | critical |
| 4 | semantics | high |
| 5 | forms and errors | high |
| 6 | announcements | medium-high |
| 7 | contrast and states | medium |
| 8 | media and motion | low-medium |
| 9 | tool boundaries | critical |
quick reference
1. accessible names (critical)
- every interactive control must have an accessible name
- icon-only buttons must have aria-label or aria-labelledby
- every input, select, and textarea must be labeled
- links must have meaningful text (no “click here”)
- decorative icons must be aria-hidden
2. keyboard access (critical)
- do not use div or span as buttons without full keyboard support
- all interactive elements must be reachable by Tab
- focus must be visible for keyboard users
- do not use tabindex greater than 0
- Escape must close dialogs or overlays when applicable
3. focus and dialogs (critical)
- modals must trap focus while open
- restore focus to the trigger on close
- set initial focus inside dialogs
- opening a dialog should not scroll the page unexpectedly
4. semantics (high)
- prefer native elements (button, a, input) over role-based hacks
- if a role is used, required aria attributes must be present
- lists must use ul or ol with li
- do not skip heading levels
- tables must use th for headers when applicable
5. forms and errors (high)
- errors must be linked to fields using aria-describedby
- required fields must be announced
- invalid fields must set aria-invalid
- helper text must be associated with inputs
- disabled submit actions must explain why
6. announcements (medium-high)
- critical form errors should use aria-live
- loading states should use aria-busy or status text
- toasts must not be the only way to convey critical information
- expandable controls must use aria-expanded and aria-controls
7. contrast and states (medium)
- ensure sufficient contrast for text and icons
- hover-only interactions must have keyboard equivalents
- disabled states must not rely on color alone
- do not remove focus outlines without a visible replacement
8. media and motion (low-medium)
- images must have correct alt text (meaningful or empty)
- videos with speech should provide captions when relevant
- respect prefers-reduced-motion for non-essential motion
- avoid autoplaying media with sound
9. tool boundaries (critical)
- prefer minimal changes, do not refactor unrelated code
- do not add aria when native semantics already solve the problem
- do not migrate UI libraries unless requested
review guidance
- fix critical issues first (names, keyboard, focus, tool boundaries)
- prefer native HTML before adding aria
- quote the exact snippet, state the failure, propose a small fix
- for complex widgets (menu, dialog, combobox), prefer established accessible primitives over custom behavior
