html coding - Part 10 - HTML Accessibility.

 

HTML Accessibility

Accessibility refers to making web pages usable by everyone, including people with disabilities.

Principles of Accessibility

1. Perceivable: Content must be perceivable by all users.
2. Operable: Navigation and interaction must be operable by all users.
3. Understandable: Content and interface must be understandable by all users.
4. Robust: Content must be robust enough to work with different technologies.

Accessibility Techniques

1. Semantic HTML: Use semantic elements to provide meaning to the structure.
2. Alt Text: Provide alternative text for images.
3. ARIA Attributes: Use ARIA attributes to provide additional information for screen readers.
4. Keyboard Navigation: Ensure that the page can be navigated using a keyboard.
5. Color Contrast: Ensure that the page has sufficient color contrast.
