E-commerce Accessibility and Inclusive Design
E-commerce accessibility ensures that all users — including those with disabilities affecting vision, hearing, motor function, or cognition — can browse, select, and purchase products. Beyond the legal requirements (WCAG 2.1 AA, Equality Act 2010 in the UK), accessibility represents a significant commercial opportunity: 1 in 5 people in the UK have a disability, and accessible sites convert better for all users.
Key WCAG Requirements for E-commerce
- Perceivable: All product images have descriptive alt text; colour contrast meets minimums (4.5:1 for body text); videos have captions
- Operable: Full site functionality via keyboard navigation; skip links to bypass navigation; no keyboard traps in modals/overlays; adequate touch target sizes (44px minimum)
- Understandable: Clear error messages in forms with specific guidance on fixing; consistent navigation; readable text (not justified, adequate line spacing)
- Robust: Works with screen readers (NVDA, JAWS, VoiceOver); ARIA attributes correctly used for dynamic content
High-Risk E-commerce Patterns
- Product colour swatches without text labels (colour-blind users can't distinguish)
- Modal overlays without focus management (screen readers can't access)
- Custom dropdown menus not accessible via keyboard
- Countdown timers that create time pressure without accessible warning
- Checkout forms with poor error handling and unclear field labelling
