Web Accessibility

Web accessibility makes websites usable by people with different abilities, devices, and contexts.

What Is Web Accessibility​

Accessibility includes semantic HTML, keyboard navigation, readable contrast, labels, focus states, and compatibility with assistive technologies.

Good accessibility also improves overall usability.

How To Use Web Accessibility​

Start with semantic HTML, test keyboard flows, provide text alternatives, and use ARIA only when native HTML is not enough.

Basic Example​

<button type="button" aria-label="Close dialog">
  X
</button>

Common Concepts​

  • Semantic elements communicate meaning.
  • Focus order should follow the page flow.
  • Form fields need accessible labels.
  • Color contrast should be readable.
