Purpose

Quick accessibility verification for every pull request. Completing these checks before requesting review prevents accessibility regressions.

Markup

• Semantic HTML elements used where possible (<nav>, <main>, <button>, etc.).
• Heading hierarchy maintained (no skipped levels).
• All images have appropriate alt text.
• ARIA attributes are used correctly (if applicable).

Keyboard

• New interactive elements are keyboard reachable.
• Focus indicator is visible.
• Tab order follows visual order.
• No keyboard traps introduced.

Forms

• Every input has an associated label.
• Error messages are linked to inputs via aria-describedby.
• Required fields are indicated.

Visual

• Colour is not the only means of conveying information.
• Colour contrast meets WCAG AA for new elements.
• Text is readable at 200% zoom.

Testing

• Automated accessibility scan passes (axe DevTools or CI tool).
• Quick screen reader spot-check performed.
