Web Accessibility: Building for Everyone

Web accessibility isn't optional – it's essential. Over 1 billion people have disabilities. Here's how to build inclusive websites.

Why Accessibility Matters

• Ethical: Everyone deserves equal access
• Legal: Many countries require it
• Business: Larger audience, better SEO
• Technical: Often improves overall UX

WCAG Guidelines

Web Content Accessibility Guidelines (WCAG) principles:

Perceivable - Text alternatives for images - Captions for videos - Sufficient color contrast - Resizable text

Operable - Keyboard navigation - Enough time to read - No seizure-inducing content - Clear navigation

Understandable - Readable text - Predictable behavior - Input assistance - Error prevention

Robust - Valid HTML - Compatible with assistive tech - Future-proof code

Practical Implementation

Semantic HTML Use proper elements: - Headings (h1-h6) in order - Lists for lists - Buttons for actions - Links for navigation

Images - Meaningful alt text - Decorative images: empty alt - Complex images: long descriptions

Forms - Labels for all inputs - Error messages - Required field indicators - Logical tab order

Color - Don't rely on color alone - Minimum contrast ratios - Test with color blindness simulators

Keyboard - All interactive elements focusable - Visible focus indicators - Logical focus order - Skip links

Testing

• Automated: axe, WAVE, Lighthouse
• Manual: Keyboard navigation
• Screen readers: NVDA, VoiceOver
• User testing with disabled users

Common Mistakes

• Missing alt text
• Poor color contrast
• Inaccessible forms
• No keyboard support
• Auto-playing media
