The Curb Cut Analogy
Curb cuts (ramps in sidewalks) were designed for wheelchairs, but help everyone:
- Parents with strollers
- People with luggage
- Delivery workers with carts
- Cyclists
Web accessibility is the same!
Designing for disabilities improves the experience for everyone.
Why It Matters
Over 1 billion people have disabilities:
- Visual → Blind, low vision, color blind
- Hearing → Deaf, hard of hearing
- Motor → Can't use mouse, limited movement
- Cognitive → Dyslexia, attention issues
Without accessibility, your website locks them out.
How People Access the Web Differently
- Screen readers → Read page aloud for blind users
- Keyboard only → No mouse, just Tab and Enter
- Voice control → Speak commands
- Screen magnifiers → Zoom in for low vision
Your website needs to work with all of these!
Simple Accessibility Wins
Images:
- Add alt text: "Golden retriever playing in park"
- Screen readers can describe images to blind users
Colors:
- Don't rely only on color (red for error)
- Good contrast between text and background
Keyboard navigation:
- Can users Tab through the page?
- Are buttons and links focusable?
Forms:
- Label every input field
- Show clear error messages
Benefits Beyond Disabilities
Accessibility helps:
- Elderly users with declining vision
- Mobile users with small screens
- Users in bright sunlight (need contrast!)
- SEO (search engines read alt text too!)
In One Sentence
Web Accessibility means designing websites so everyone, including people with disabilities, can use them—and it makes sites better for everyone.
