Web Accessibility: Building Inclusive Digital Experiences 🌍🛠️

Web accessibility ensures all users, including those with disabilities, can perceive, understand, navigate, and interact with digital content. Here's a guide for developers:

Why It Matters

• Equal Access: 1 in 4 people have a disability, making accessibility a moral imperative 🧠
• Legal Compliance: ADA, WCAG, and other standards require inclusive design 📜
• Broader Reach: Improves usability for all users, including older adults and those with temporary impairments 👨‍🦳

Core Principles (WCAG)

1. Perceivable 🖥️
   • Use alt text for images: <img src="..." alt="Descriptive text">
   • Add captions to videos
2. Operable 👨‍💻
   • Ensure keyboard navigation support
   • Avoid time-sensitive content without alternatives
3. Understandable 📚
   • Use clear language and predictable navigation
   • Provide error messages and instructions
4. Robust 🔗
   • Ensure compatibility with current and future technologies

Practical Tips

• Test with screen readers like NVDA or VoiceOver
• Use ARIA roles for complex UI components
• Check contrast ratios (minimum 4.5:1 for normal text)
• Implement proper heading hierarchies

Tools to Help

• WAVE for quick audits
