Accessibility Audit: $ARGUMENTS

If $ARGUMENTS is empty, ask the user for a component path or folder before proceeding.

Audit the component(s) at $ARGUMENTS for WCAG AA compliance. Check both the component implementation and its documentation examples.

Checklist

1. Semantic HTML

• Interactive elements use native HTML (<button>, <a>, <input>) — not <div> or <span> with click handlers
• Lists use <ul>/<ol>/<li> — not divs with list styling
• Headings use <h1>-<h6> with correct hierarchy
• Tables use <table>, <thead>, <tbody>, <th> with scope

2. ARIA Attributes

• Custom interactive components have appropriate role attribute
• aria-label or aria-labelledby on elements without visible text
• aria-expanded on expandable triggers (menus, dropdowns, accordions)
• aria-selected on selectable items (tabs, list items)
• aria-disabled synced with disabled input
• aria-haspopup on elements that open popups/menus
• aria-live regions for dynamic content updates
• No redundant ARIA (e.g. role="button" on <button>)

3. Keyboard Navigation

• All interactive elements reachable via Tab
• Tab order follows visual/logical order
• Arrow keys for navigation within composite widgets (menus, tabs, grids)
• Enter/Space activates buttons and links
• Escape closes modals, popups, and dropdowns
• Focus trapped inside modals/dialogs when open
• Focus returns to trigger element when popup/modal closes
• No keyboard traps (user can always Tab out)

4. Focus Management

• Focus indicator visible on all interactive elements (:focus-visible styles)
• Focus moves to new content when dynamically added (e.g. dialog opens)
• tabindex="0" only on elements that need to be in tab order
• tabindex="-1" for programmatically focusable elements not in tab order
• No positive tabindex values (breaks natural tab order)

5. Color and Contrast

• Text meets 4.5:1 contrast ratio (normal text) or 3:1 (large text)
• Information not conveyed by color alone (icons, patterns, or text as backup)
• Focus indicators meet 3:1 contrast ratio
• Disabled states still readable (though not required to meet full contrast)

6. Screen Reader Compatibility

• Meaningful alt text on images (or alt="" for decorative)
• Form inputs have associated <label> or aria-label
• Error messages associated via aria-describedby
• Status changes announced via aria-live or role="status"
• Hidden decorative elements have aria-hidden="true"

7. Documentation Examples

• Examples are keyboard-navigable when rendered
• Examples include tabindex where needed for non-native interactive elements
• Examples demonstrate accessible usage patterns
