Accessibility

Web accessibility ensures that websites and web applications are usable by people with disabilities. It involves creating content that is accessible to everyone, regardless of their abilities.

To enhance accessibility:

  1. Use Semantic HTML: Utilize appropriate HTML elements (e.g., <header>, <nav>, <main>, <footer>) to convey the content structure.

  2. Provide Descriptive Alt Text: Include meaningful alt text for images to communicate their purpose to visually impaired users.

  3. Implement ARIA Attributes: Use Accessible Rich Internet Applications (ARIA) attributes to convey additional context to assistive technologies like screen readers.

Example:

<button aria-label="Play">
  <img src="play-button.png">
</button>

In this example, the aria-label="Play" provides a text label for the button, which assists screen reader users.

Other Common ARIA Attributes:

  • role="button": Indicates that an element should be treated as a button.
  • aria-disabled="true": Signals that an element is disabled.
  • aria-expanded="true": Indicates that an element is expanded (e.g., for a collapsible section).
  • aria-selected="true": Shows that an item is selected (e.g., within a list).
