Accessibility isn’t just about checking boxes - it’s about creating experiences that work for everyone.

Why Accessibility Matters

Over 1 billion people worldwide have some form of disability. But accessibility isn’t just about helping those users - it improves the experience for everyone.

Core Principles

1. Perceivable

Can users perceive all the information your app provides?

  • Provide alt text for images
  • Ensure sufficient color contrast
  • Offer text alternatives for non-text content

2. Operable

Can users navigate and use your interface?

  • All features should be keyboard accessible
  • Give users enough time to read content
  • Don’t rely on color alone to convey information

3. Understandable

Is your interface easy to understand?

  • Use clear, simple language
  • Be consistent in navigation and design
  • Provide helpful error messages

4. Robust

Does your content work across different technologies?

  • Follow web standards
  • Test with assistive technologies
  • Provide proper HTML semantics
