Overview

LamaPress follows WCAG 2.1 AA standards for accessibility, ensuring websites are usable by people with disabilities.

WCAG Standards

Level AA Compliance

LamaPress aims for WCAG 2.1 Level AA compliance:

• Perceivable - Information is presentable to users
• Operable - Interface components are navigable
• Understandable - Information is readable
• Robust - Content is interpretable by assistive technologies

Key Requirements

• Color contrast ratio: 4.5:1 for normal text, 3:1 for large text
• Keyboard navigation for all interactive elements
• Focus indicators visible
• Alt text for images
• Proper heading hierarchy
• Form labels associated with inputs

Implementation Guidelines

Semantic HTML

Use semantic HTML elements:

<header>
  <nav>
    <ul>
      <li><a href="/">Home</a></li>
    </ul>
  </nav>
</header>

<main>
  <article>
    <h1>Article Title</h1>
    <p>Content</p>
  </article>
</main>

<footer>
  <p>Footer content</p>
</footer>

ARIA Attributes

Use ARIA when needed:

<button aria-label="Close menu" aria-expanded="false">
  <span aria-hidden="true">×</span>
</button>

Keyboard Navigation

Ensure keyboard navigation works:

• All interactive elements focusable
• Tab order logical
• Focus indicators visible
• Skip links provided

Color Contrast

Ensure sufficient contrast:

• Normal text: 4.5:1 minimum
• Large text: 3:1 minimum
• Interactive elements: Clear focus states

Component Accessibility

Interactive Components

Make interactive components accessible:

<button 
  class="js-toggle" 
  aria-label="Toggle menu"
  aria-expanded="false"
  aria-controls="menu"
>
  Menu
</button>

Form Components

Accessible forms:

<label for="email">Email</label>
<input 
  type="email" 
  id="email" 
  name="email" 
  required
  aria-describedby="email-error"
>
<span id="email-error" class="error" role="alert"></span>

Media Components

Accessible media:

<img 
  src="image.jpg" 
  alt="Descriptive alt text"
  loading="lazy"
>

<video controls aria-label="Video description">
  <source src="video.mp4" type="video/mp4">
</video>

Testing

Automated Testing

Use automated tools:

• Lighthouse (Chrome DevTools)
• axe DevTools
• WAVE browser extension

Manual Testing

Manual testing:

• Keyboard navigation
• Screen reader testing
• Color contrast checking

Screen Reader Testing

Test with screen readers:

• NVDA (Windows)
• VoiceOver (macOS)
• JAWS (Windows)

Best Practices

1. Use Semantic HTML

Always use semantic HTML:

• <header>, <nav>, <main>, <footer>
• <article>, <section>
• Proper heading hierarchy (<h1> to <h6>)

2. Provide Alt Text

Always provide alt text for images:

• Descriptive and meaningful
• Context-appropriate
• Empty alt for decorative images: alt=""

3. Test with Screen Readers

Regularly test with screen readers:

• Verify navigation
• Check announcements
• Ensure content is understandable
