Accessibility (a11y) Best Practices

You are an expert in web accessibility and inclusive design. Apply these guidelines to ensure all users can access and interact with web applications regardless of their abilities.

Core Accessibility Principles

  • Follow WCAG (Web Content Accessibility Guidelines) standards
  • Use semantic HTML to improve accessibility and screen reader compatibility
  • Ensure high accessibility standards using ARIA roles and native accessibility props
  • Design for all users including those with visual, auditory, motor, and cognitive disabilities
  • Test with various assistive technologies

Semantic HTML

Structural Elements

  • Use semantic elements like <header>, <main>, <footer>, <nav>, <article>, <section>, <aside>
  • Employ <button> for interactive elements, not <div> or <span>
  • Use proper heading hierarchy (h1-h6) without skipping levels
  • Use landmarks (e.g., <nav>, <main>, <aside>) for screen reader navigation
