♿ Component Accessibility

Button Component

Keyboard Navigation

// ✅ Proper keyboard support
<Button 
  variant="primary"
  onKeyDown={(e) => {
    if (e.key === 'Enter' || e.key === ' ') {
      e.preventDefault()
      handleClick()
    }
  }}
>
  Click Me
</Button>

Screen Reader Support

// ✅ Descriptive labels
<Button 
  variant="primary"
  aria-label="Book activity for children aged 5-8"
  aria-describedby="activity-description"
>
  Book Activity
</Button>
<p id="activity-description">
  This activity helps develop motor skills and creativity
</p>

Focus Management

// ✅ Visible focus indicators
<Button 
  variant="primary"
  className="focus:ring-2 focus:ring-[#FF6B35] focus:ring-offset-2"
>
  Focusable Button
</Button>

Input Component

Form Labels

// ✅ Associated labels
<Input
  id="email-input"
  label="Email Address"
  aria-describedby="email-help"
  aria-invalid={hasError}
  aria-errormessage={error ? "email-error" : undefined}
/>
{error && (
  <div id="email-error" role="alert" className="text-[#DC3545]">
    {error}
  </div>
)}

Error States

// ✅ Clear error communication
<Input
  variant="error"
  aria-invalid="true"
  aria-errormessage="email-error"
/>
<div id="email-error" role="alert">
  Please enter a valid email address
</div>

Card Component

Semantic Structure

// ✅ Proper heading hierarchy
<Card>
  <CardHeader>
    <CardTitle as="h2">Activity Details</CardTitle>
    <CardDescription>Information about the selected activity</CardDescription>
  </CardHeader>
  <CardContent>
    <p>Activity content here...</p>
  </CardContent>
</Card>

🎨 Visual Accessibility

Color Contrast

All color combinations meet WCAG 2.1 AA standards:

Text Color	Background Color	Contrast Ratio	WCAG Level
#1A1A1A	#FFFFFF	15.6:1	AAA
#6C757D	#FFFFFF	4.5:1	AA
#FFFFFF	#FF6B35	3.2:1	AA
#FFFFFF	#28A745	3.1:1	AA
#FFFFFF	#DC3545	3.9:1	AA

Focus Indicators

Consistent focus indicators across all interactive elements:

/* Global focus styles */
*:focus-visible {
  outline: 2px solid #FF6B35;
  outline-offset: 2px;
}

/* Component-specific focus */
.button:focus-visible {
  ring: 2px;
  ring-color: #FF6B35;
  ring-opacity: 0.2;
}

Typography

Accessible typography with proper line heights and spacing:

/* Readable text */
.text-sm {
  font-size: 0.875rem;
  line-height: 1.5;
  letter-spacing: 0.025em;
}

/* Large text for better readability */
.text-lg {
  font-size: 1.125rem;
  line-height: 1.75;
}

🔧 ARIA Implementation

Landmarks

Proper use of ARIA landmarks for navigation:

// ✅ Main content area
<main role="main" aria-label="Activity booking page">
  <h1>Book an Activity</h1>
  {/* Page content */}
</main>

// ✅ Navigation
<nav role="navigation" aria-label="Primary navigation">
  <ul>
    <li><a href="/activities">Activities</a></li>
    <li><a href="/bookings">Bookings</a></li>
  </ul>
</nav>

Live Regions

For dynamic content updates:

// ✅ Status updates
<div role="status" aria-live="polite" aria-atomic="true">
  {bookingStatus}
</div>

// ✅ Error announcements
<div role="alert" aria-live="assertive">
  {errorMessage}
</div>

Form Labels

Proper form labeling and descriptions:

// ✅ Complex form controls
<div>
  <label htmlFor="activity-type">Activity Type</label>
  <select 
    id="activity-type"
    aria-describedby="activity-help"
  >
    <option value="">Select an activity</option>
    <option value="sports">Sports</option>
    <option value="arts">Arts & Crafts</option>
    <option value="childcare">Childcare</option>
    <option value="parties">Parties & Events</option>
  </select>
  <p id="activity-help">
    Choose the type of activity your child would enjoy
  </p>
</div>

🧪 Testing

Automated Testing

import { axe, toHaveNoViolations } from 'jest-axe'

// Test component accessibility
test('meets accessibility standards', async () => {
  const { container } = render(<MyComponent />)
  const results = await axe(container)
  expect(results).toHaveNoViolations()
})

// Test specific accessibility rules
test('has proper heading structure', async () => {
  const { container } = render(<MyComponent />)
  const results = await axe(container, {
    rules: {
      'heading-order': { enabled: true },
      'page-has-heading-one': { enabled: true }
    }
  })
  expect(results).toHaveNoViolations()
})

🎯 Best Practices

Do's

✅ Provide Clear Labels

// ✅ Good
<Button aria-label="Book activity for children aged 5-8">
  Book Activity
</Button>

✅ Use Semantic HTML

// ✅ Good
<button type="submit">Submit Form</button>
<nav role="navigation">Navigation</nav>

✅ Include Error Messages

// ✅ Good
<Input 
  aria-invalid="true"
  aria-errormessage="email-error"
/>
<div id="email-error" role="alert">
  Please enter a valid email address
</div>

✅ Provide Focus Indicators

// ✅ Good
<Button className="focus:ring-2 focus:ring-[#FF6B35]">
  Focusable Button
</Button>

Don'ts

❌ Don't Rely on Color Alone

// ❌ Bad
<div style={{ color: 'red' }}>Error occurred</div>

// ✅ Good
<div>
  <Icon name="alert" />
  <span>Error occurred</span>
</div>

❌ Don't Use Generic Text

// ❌ Bad
<Button>Click here</Button>

// ✅ Good
<Button>Book Activity</Button>

❌ Don't Skip Focus Management

// ❌ Bad
<div onClick={handleClick}>Clickable div</div>

// ✅ Good
<Button onClick={handleClick}>Clickable button</Button>
