Introduction

Accessibility ensures websites can be used by everyone — including people with disabilities, screen readers, keyboard-only navigation, and more. It’s required for professional websites and drastically improves usability.

1. Using Alt Text

Alt text explains the image to screen readers.

2. Proper Headings Structure

Main Title
Section
Sub-section
    

Headings must be hierarchical to help assistive technologies navigate the page.

3. Labels for Inputs

4. ARIA Roles

ARIA improves how screen readers interpret your layout.

5. Keyboard-Friendly Navigation

button:focus {
  outline: 2px solid #64b5f6;
}
    

Never remove outlines unless you replace them with something visible.

6. Using tabindex

Focusable block
    

Makes non-interactive elements reachable via keyboard. Use sparingly.

7. Accessible Forms

8. Color Contrast

Contrast must be readable — WCAG recommends a minimum contrast ratio of 4.5:1.

9. Landmarks
