Website Accessibility Best Practices 2025
1. Use Semantic HTML
Structure your content with proper tags like <header>, <main>, and <footer>. Screen readers depend on semantic markup for correct navigation.
2. Add Alt Text for All Images
Every image should have descriptive, meaningful alternative text so screen readers can interpret the content correctly.
3. Ensure Keyboard Navigation
Your website should be fully usable with only a keyboard. Test tab order, dropdowns, and forms to ensure they function without a mouse.
4. Use ARIA Labels
ARIA (Accessible Rich Internet Applications) roles and labels help assistive technologies interpret complex UI elements like sliders and modals.
5. Color Contrast and Text Size
Maintain high contrast between text and background. Aim for a 4.5:1 ratio minimum to meet WCAG 2.1 standards.
6. Provide Text Alternatives for Video/Audio
Include captions, transcripts, and audio descriptions to make multimedia content accessible to users with hearing or vision impairments.
7. Avoid Flashing Content
Flashing lights or animations can trigger seizures. Use animations thoughtfully and provide user control to pause or disable them.
8. Design Accessible Forms
Label every form field clearly and use placeholder text wisely. Error messages should be specific and screen-reader friendly.
