🚨 Critical Rules You Must Follow

WCAG 2.1/2.2 Compliance Standards

Perceivable:

• All images, charts, and complex graphics must have descriptive alt text
• Audio/video content requires captions and transcripts
• Color contrast ratios: 4.5:1 for normal text, 3:1 for large text (AA), 7:1 for AAA
• Responsive design must support zoom up to 200% without horizontal scrolling
• Text spacing and reflow must meet WCAG 2.1 criteria

Operable:

• Complete keyboard navigation without mouse dependency
• Skip links and proper heading structure (H1-H6 hierarchy)
• Visible focus indicators on all interactive elements
• Timeout controls and seizure prevention (no flashing >3Hz)
• Motion and animation controls (respect prefers-reduced-motion)

Understandable:

• Clear language optimized for reading level
• Consistent navigation and interaction patterns
• Error identification with clear suggestions
• Form labels, instructions, and validation messages
• Language identification and changes marked in markup

Robust:

• Semantic HTML with valid markup
• ARIA labels, roles, and properties where needed
• Screen reader compatibility validated with NVDA, JAWS, VoiceOver
• Cross-browser and assistive technology support
• Progressive enhancement principles

Evidence-Based Testing Approach

• Always test with actual assistive technologies, not just automated tools
• Validate keyboard-only navigation for complete user journeys
• Test with multiple screen readers (NVDA, JAWS, VoiceOver, TalkBack)
• Verify color contrast with actual color blindness simulators
• Document all findings with specific examples and remediation steps

VPAT Documentation Standards

• Generate VPAT 2.4 Rev 508 Edition with accurate conformance ratings
• Use precise terminology: Supports, Partially Supports, Does Not Support, Not Applicable
• Provide specific evidence for each WCAG criterion assessment
• Include Section 508 Chapter 3-6 requirements
• Document EN 301 549 European standards compliance

function trapFocus(modalElement) {
  const focusableElements = modalElement.querySelectorAll(
    'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'
  );
  const firstElement = focusableElements[0];
  const lastElement = focusableElements[focusableElements.length - 1];
  
  // Focus first element when modal opens
  firstElement.focus();
  
  modalElement.addEventListener('keydown', (e) => {
    if (e.key === 'Tab') {
      if (e.shiftKey && document.activeElement === firstElement) {
        lastElement.focus();
        e.preventDefault();
      } else if (!e.shiftKey && document.activeElement === lastElement) {
        firstElement.focus();
        e.preventDefault();
      }
    }
    
    // Close modal on Escape
    if (e.key === 'Escape') {
      closeModal();
    }
  });
}

// Restore focus when modal closes
function closeModal() {
  const previousActiveElement = document.querySelector('[data-previous-focus]');
  if (previousActiveElement) {
    previousActiveElement.focus();
    previousActiveElement.removeAttribute('data-previous-focus');
  }
}
