Introduction
Web accessibility is not just about compliance. It is about creating digital experiences that work for the 1.3 billion people worldwide who live with disabilities. With WCAG 2.2 now the current standard and legal requirements tightening globally, accessibility must be a core consideration in every web project.
WCAG 2.2 Core Principles
WCAG 2.2 is built on four principles, known as POUR. Every guideline falls under one of these categories.
👁️Perceivable
Information and UI components must be presentable in ways users can perceive.
- Provide text alternatives for non-text content
- Provide captions and alternatives for multimedia
- Create content that can be presented in different ways
- Make it easier for users to see and hear content
🖱️Operable
UI components and navigation must be operable by all users.
- Make all functionality available from a keyboard
- Give users enough time to read and use content
- Do not use content that causes seizures
- Help users navigate and find content
🧠Understandable
Information and UI operation must be understandable.
- Make text readable and understandable
- Make pages appear and operate in predictable ways
- Help users avoid and correct mistakes
🔧Robust
Content must be robust enough for diverse user agents.
- Maximize compatibility with current and future tools
- Use valid, semantic HTML
- Ensure proper ARIA implementation when needed
🆕New in WCAG 2.2
WCAG 2.2 introduced several new success criteria. Key additions include:
- Focus Not Obscured:Focused elements must be at least partially visible
- Focus Appearance:Focus indicators must be clearly visible
- Dragging:Drag operations must have single-pointer alternatives
- Target Size:Interactive targets must be at least 24x24 pixels
Common Accessibility Issues
These issues appear on millions of websites. Address them to significantly improve your accessibility score.
⚠️Top 10 Accessibility Failures
- Missing or poor alt text on images
- Insufficient color contrast (text/background)

Testing Tools and Methods
Use a combination of automated and manual testing to ensure comprehensive accessibility coverage.
🛠️Recommended Testing Tools
⚡Quick Manual Tests
Run these tests on every page before launch:
- Navigate using only Tab, Enter, and Escape keys
- Zoom to 200% and check layout breaks
- Disable CSS and verify content order makes sense

Legal Considerations
Accessibility is increasingly becoming a legal requirement. Understanding the legal landscape helps protect your business.

- EAA (European Accessibility Act):EU directive effective June 2025 for products and services
- Section 508:US federal agencies and contractors must meet WCAG 2.0 AA
- AODA:Ontario accessibility legislation requiring WCAG 2.0 AA

✅Implementation Checklist
- Add meaningful alt text to all images
- Ensure color contrast meets 4.5:1 ratio
- Label all form inputs properly
