Building Accessible Web Applications

The Importance of Accessibility

Web accessibility ensures that people with disabilities can use your website. It's not just the right thing to do—it's also required by law in many jurisdictions.

Core Principles (POUR)

• Perceivable - Users can perceive the information
• Operable - Users can operate the interface
• Understandable - Users can understand the content
• Robust - Content works across technologies

Practical Tips

1. Use semantic HTML elements
2. Provide text alternatives for images
3. Ensure keyboard navigation works
4. Use ARIA attributes correctly
5. Test with screen readers

Example: Accessible Form

<form>
  <label htmlFor="email">Email Address</label>
  <input 
    id="email"
    type="email"
    aria-describedby="email-help"
    required
  />
  <span id="email-help" className="text-sm">
    We'll never share your email
  </span>
</form>

Making your website accessible benefits everyone and improves the overall user experience.
