Why Accessibility Matters
1 billion people worldwide have disabilities. Inaccessible websites exclude potential customers, employees, and partners. Beyond ethics, there are legal and business reasons to prioritize accessibility.
Legal Requirements
- ADA (US): Courts have ruled websites are places of public accommodation
- Section 508: Federal agencies must be accessible
- WCAG: International standard with legal weight in many countries
Lawsuits against inaccessible websites have increased dramatically. Prevention is cheaper than litigation.
The Business Case
- Market expansion: 15-20% of potential users have disabilities
- SEO benefits: Accessible sites often rank better
- Mobile experience: Many accessibility features improve mobile UX
- Brand reputation: Inclusivity matters to customers
WCAG Principles (POUR)
Perceivable
Content must be presentable in ways users can perceive:
- Alt text for images
- Captions for videos
- Sufficient color contrast
- Text alternatives for non-text content
Operable
Interface must be operable by all users:
- Keyboard navigation
- Enough time for interactions
- No seizure-triggering content
- Clear navigation structure
Understandable
Content and interface must be understandable:
- Readable text
- Predictable behavior
- Input assistance
- Error identification
Robust
Content must be robust enough for all technologies:
- Valid HTML
- Proper ARIA usage
- Compatible with assistive technologies
- Future-proof coding
Practical Implementation
Semantic HTML
<!-- Bad --> <div class="button" onclick="submit()">Submit</div> <!-- Good --> <button type="submit">Submit</button>
Form Labels
<!-- Bad --> <input placeholder="Email" /> <!-- Good --> <label for="email">Email</label> <input id="email" type="email" />
Color Contrast
- Normal text: 4.5:1 minimum ratio
- Large text: 3:1 minimum ratio
- Don't rely on color alone for meaning
Keyboard Navigation
- All interactive elements focusable
- Visible focus indicators
- Logical tab order
- Skip links for navigation
ARIA When Needed
<button aria-expanded="false" aria-controls="menu" > Menu </button>
Testing for Accessibility
