Accessibility Audit (a11y-audit)

Audits UI or designs against WCAG 2.2 AA/AAA and ARIA patterns, returning criterion-referenced findings with severity and concrete fixes.

Design & UIIntermediate★ 1,458⑂ 151AI score 7/10Last updated: Sep 16, 2026

What it does

  • Reviews a UI against WCAG 2.2, including the newer criteria: Focus Not Obscured (2.4.11), Target Size (2.5.8), Accessible Authentication (3.3.8).
  • Checks a mandatory P0 set per component: keyboard navigability, visible focus (≥3:1), screen-reader name/role/state, contrast (4.5:1 text / 3:1 UI), ≥24×24 targets, and no color-only signaling.
  • Measures contrast with real scripts instead of eyeballing (measure_render.mjs, verify_states.mjs, contrast.py), covering default/hover/focus states so hover-only failures get caught.
  • Outputs a findings table: WCAG criterion · severity (P0/P1/P2) · what fails · specific fix, plus explicit confirmation of passes.

Who it's for

  • Front-end engineers, UI/UX designers, design-system owners.
  • Teams under accessibility compliance requirements (public sector, finance, enterprise procurement).
  • Anyone adding an accessibility gate to pre-release QA.

Examples

  1. "Audit this modal component" → findings on focus trap, close-button accessible name, ESC handling, each mapped to a WCAG criterion.
  2. "Does the button pass contrast in dark mode?" → runs verify_states.mjs --dark and flags only the failing state.
  3. "Is #767676 on white AA-compliant?" → contrast.py gives the measured ratio and suggested alternatives.
