WCAG 2.1 Level AA/AAA Compliance Achieved

Image Accessibility Excellence

Every single image on the platform now has contextually meaningful alt text, not generic placeholders. We built a centralized backend system with dedicated model methods that automatically generate descriptive alt text:

  • Profile avatars identify the user by name
  • Topic cover images reference the topic title
  • Post images attribute to the author who uploaded them

This isn't just ticking a compliance box—it creates a genuinely accessible experience for screen reader users.

🏗️ Semantic HTML Architecture

The entire platform now uses proper HTML5 semantic structure.

Screen readers can now understand and navigate the site's structure intuitively.

♿ Comprehensive ARIA Implementation

Every interactive element has been enhanced with ARIA attributes.

The platform now speaks the language of assistive technologies fluently.

⌨️ Full Keyboard Navigation Support

100% keyboard accessible without requiring a mouse:

  • Skip navigation link appears on Tab focus (WCAG 2.4.1 compliance)
  • All interactive elements reachable via Tab/Shift+Tab
  • Proper focus indicators visible throughout
  • No keyboard traps anywhere on the site
  • Enter/Space activation for all buttons and controls

Power users and accessibility tool users can navigate at full speed.

📱 Touch Target Optimization for Mobile

Implemented WCAG 2.1 Level AAA touch target sizing:

  • Desktop: Minimum 44×44px for all interactive elements
  • Mobile: Enhanced to 48×48px for critical actions like likes and settings
