2. Design responsive layouts:

   • Content reflows at 320px width
   • Text scales to 200% without horizontal scrolling
   • Touch targets minimum 44×44px
   • Adequate white space between elements

Step 5: Design Accessible Navigation

Keyboard Navigation Design

1. Clear focus indicators:

   • High contrast focus outlines
   • Consistent focus styling across site
   • Never remove focus indicators completely

2. Logical tab order:

   • Left-to-right, top-to-bottom flow
   • Skip links to main content
   • Modal dialogs trap focus appropriately

Information Architecture

1. Meaningful page titles:

   • Unique titles for each page
   • Describe page purpose clearly
   • Include site name consistently

2. Clear heading hierarchy:

   • One H1 per page
   • Sequential heading levels (don't skip)
   • Descriptive heading text

Step 6: Design Accessible Components

Forms

1. Clear labels and instructions:

   • Every input has associated label
   • Required fields clearly marked
   • Input format explained (dates, phone numbers)
   • Error messages specific and helpful

2. Logical form structure:

   • Group related fields with fieldset/legend
   • Place labels above inputs (not beside)
   • Provide clear submission feedback

Interactive Elements

1. Accessible buttons and links:

   • Descriptive button text (not "click here")
   • Link purpose clear from text alone
   • Sufficient size for touch targets

2. Custom component patterns:

   • Follow established ARIA design patterns

Phase 3: Develop Accessible Code (Weeks 4-6)

Step 7: Implement Semantic HTML

HTML Structure Foundation

<!-- Proper document structure -->
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Unique Page Title - Site Name</title>
</head>
<body>
  <header>
    <nav aria-label="Main navigation">
      <!-- Navigation content -->
    </nav>
  </header>
  
  <main>
    <h1>Page Main Heading</h1>
    <!-- Page content -->
  </main>
  
  <footer>
    <!-- Footer content -->
  </footer>
</body>
</html>

Semantic Elements Checklist

• [ ] Use heading elements (h1-h6) for structure, not styling
• [ ] Mark up lists with ul/ol and li elements
• [ ] Use semantic elements: header, nav, main, section, article, aside, footer
• [ ] Tables use th, caption, and scope attributes appropriately
• [ ] Forms use label, fieldset, and legend elements correctly

Step 8: Implement ARIA (Accessible Rich Internet Applications)

Essential ARIA Patterns

<!-- Form with live validation -->
<label for="email">Email Address (required)</label>
<input type="email" id="email" aria-required="true" aria-describedby="email-error">
<div id="email-error" aria-live="polite" aria-atomic="true">
  <!-- Error messages appear here -->
</div>

<!-- Expandable accordion -->
<button aria-expanded="false" aria-controls="panel1" id="btn1">
  Section 1
</button>
<div id="panel1" aria-labelledby="btn1" hidden>
  Panel content here
</div>

<!-- Modal dialog -->
<div role="dialog" aria-labelledby="dialog-title" aria-modal="true">
  <h2 id="dialog-title">Dialog Title</h2>
  <!-- Dialog content -->
</div>

ARIA Implementation Guidelines

1. Use semantic HTML first, ARIA second
2. Don't change semantics with ARIA unless necessary
3. Ensure all interactive elements are keyboard accessible
4. Test with screen readers before deployment

Step 9: Handle Images and Media Accessibility

Image Accessibility

<!-- Informative image -->
<img src="chart.png" alt="Sales increased 23% from Q1 to Q2 2025">

<!-- Decorative image -->
<img src="decoration.png" alt="" role="presentation">

<!-- Complex image -->
<img src="complex-chart.png" alt="Quarterly sales data" aria-describedby="chart-desc">
<div id="chart-desc">
  Detailed description: Q1 sales were $2.3M, Q2 sales reached $2.8M, 
  representing a 23% increase...
</div>

Video and Audio Accessibility

1. Provide captions for all video content
2. Add audio descriptions for visual information
3. Include transcripts for audio-only content
4. Ensure media controls are keyboard accessible

Step 10: Implement Keyboard Navigation

Keyboard Support Checklist

• [ ] All interactive elements focusable with Tab key
• [ ] Tab order follows logical sequence
• [ ] Enter/Space activate buttons and links
• [ ] Arrow keys navigate within components (menus, tabs)
• [ ] Escape key closes dialogs and dropdowns
• [ ] Focus visible on all interactive elements

Focus Management Code Examples

// Modal dialog focus management
function openModal(modalId) {
  const modal = document.getElementById(modalId);
  const previousFocus = document.activeElement;
  
  modal.style.display = 'block';
  modal.querySelector('button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])').focus();
  
  // Store previous focus for restoration
  modal.setAttribute('data-previous-focus', previousFocus.id);
}

function closeModal(modalId) {
  const modal = document.getElementById(modalId);
  const previousFocusId = modal.getAttribute('data-previous-focus');
  
  modal.style.display = 'none';
  
  if (previousFocusId) {
    document.getElementById(previousFocusId).focus();
  }
}

// Skip link implementation
function addSkipLink() {
  const skipLink = document.createElement('a');
  skipLink.href = '#main';
  skipLink.textContent = 'Skip to main content';
  skipLink.className = 'skip-link';
  
  document.body.insertBefore(skipLink, document.body.firstChild);
}

Phase 4: Content Accessibility (Week 7)

Step 11: Write Accessible Content

Clear Language Guidelines

1. Use plain language:
