Audit a design or page for WCAG 2.1 AA accessibility compliance.

WCAG 2.1 AA Quick Reference

Perceivable

• 1.1.1 Non-text content has alt text

• 1.3.1 Info and structure conveyed semantically

• 1.4.3 Contrast ratio >= 4.5:1 (normal text), >= 3:1 (large text)

• 1.4.11 Non-text contrast >= 3:1 (UI components, graphics)

Operable

• 2.1.1 All functionality available via keyboard

• 2.4.3 Logical focus order

• 2.4.7 Visible focus indicator

• 2.5.5 Touch target >= 44x44 CSS pixels

Understandable

• 3.2.1 Predictable on focus (no unexpected changes)

• 3.3.1 Error identification (describe the error)

• 3.3.2 Labels or instructions for inputs

Robust

• 4.1.2 Name, role, value for all UI components

Testing Approach

• Automated scan (catches ~30% of issues)

• Keyboard-only navigation

• Screen reader testing (VoiceOver, NVDA)

• Color contrast verification

• Zoom to 200% — does layout break?

Output

| [Element] | [Order] | [Behavior] | [Behavior] | [Behavior] |

### Screen Reader
| Element | Announced As | Issue |
|---------|-------------|-------|
| [Element] | [What SR says] | [Problem if any] |

### Priority Fixes
1. **[Critical fix]** — Affects [who] and blocks [what]
2. **[Major fix]** — Improves [what] for [who]
3. **[Minor fix]** — Nice to have

If Connectors Available

If ~~design tool is connected:

• Inspect color values, font sizes, and touch targets directly from Figma

• Check component ARIA roles and keyboard behavior in the design spec

If ~~project tracker is connected:

• Create tickets for each accessibility finding with severity and WCAG criterion

• Link findings to existing accessibility remediation epics

Tips

• Start with contrast and keyboard — These catch the most common and impactful issues.

• Test with real assistive technology — My audit is a great start, but manual testing with VoiceOver/NVDA catches things I can't.

• Prioritize by impact — Fix issues that block users first, polish later.
