Responsive Design Patterns

Mobile-First Breakpoints

/* Mobile First Approach */
.responsive-grid {
  display: grid;
  grid-template-columns: 1fr;
  gap: var(--spacing-layout-sm);
}

@media (min-width: 640px) {
  .responsive-grid {
    grid-template-columns: repeat(2, 1fr);
    gap: var(--spacing-layout-md);
  }
}

@media (min-width: 1024px) {
  .responsive-grid {
    grid-template-columns: repeat(3, 1fr);
    gap: var(--spacing-layout-lg);
  }
}

@media (min-width: 1280px) {
  .responsive-grid {
    grid-template-columns: repeat(4, 1fr);
  }
}

Container Queries (Future Enhancement)

/* Container Queries for Component-Level Responsiveness */
@container (min-width: 300px) {
  .card {
    display: flex;
    flex-direction: row;
  }
  
  .card-image {
    flex: 0 0 40%;
  }
  
  .card-body {
    flex: 1;
  }
}

Accessibility Patterns

Focus Management

/* Enhanced Focus Styles */
.focus-visible {
  outline: 2px solid var(--border-focus);
  outline-offset: 2px;
}

/* Skip Links */
.skip-link {
  position: absolute;
  top: -40px;
  left: 6px;
  background: var(--bg-elevated);
  color: var(--text-primary);
  padding: 8px;
  text-decoration: none;
  border-radius: var(--radius-md);
  z-index: 1000;
}

.skip-link:focus {
  top: 6px;
}

ARIA Patterns

<!-- Accessible Modal -->
<div role="dialog" 
     aria-modal="true" 
     aria-labelledby="modal-title"
     aria-describedby="modal-description">
  <h2 id="modal-title">Modal Title</h2>
  <p id="modal-description">Modal description</p>
</div>

<!-- Accessible Form -->
<form novalidate>
  <div class="form-group">
    <label for="email" class="form-label">
      Email Address
      <span aria-label="required">*</span>
    </label>
    <input type="email" 
           id="email" 
           name="email"
           class="form-input"
           aria-describedby="email-error"
           aria-invalid="false"
           required>
    <div id="email-error" 
         class="form-error" 
         role="alert" 
         aria-live="polite">
    </div>
  </div>
</form>

Animation Patterns

Micro-Interactions

/* Button Hover Effects */
.btn {
  position: relative;
  overflow: hidden;
}

.btn::before {
  content: '';
  position: absolute;
  top: 0;
  left: -100%;
  width: 100%;
  height: 100%;
  background: linear-gradient(90deg, transparent, rgba(255,255,255,0.2), transparent);
  transition: left var(--duration-300) var(--ease-out);
}

.btn:hover::before {
  left: 100%;
}

/* Card Hover Effects */
.card-hover {
  transition: all var(--transition-base);
}

.card-hover:hover {
  transform: translateY(-4px);
  box-shadow: var(--shadow-lg);
}

.card-hover:hover .card-image img {
  transform: scale(1.05);
}

Loading States

/* Skeleton Loading */
.skeleton {
  background: linear-gradient(90deg, var(--color-neutral-200) 25%, var(--color-neutral-100) 50%, var(--color-neutral-200) 75%);
  background-size: 200% 100%;
  animation: skeleton-loading 1.5s infinite;
}

@keyframes skeleton-loading {
  0% { background-position: 200% 0; }
  100% { background-position: -200% 0; }
}

.dark .skeleton {
  background: linear-gradient(90deg, var(--color-neutral-700) 25%, var(--color-neutral-600) 50%, var(--color-neutral-700) 75%);
  background-size: 200% 100%;
}

/* Spinner Animation */
.spinner {
  width: 1rem;
  height: 1rem;
  border: 2px solid var(--color-neutral-200);
  border-top: 2px solid var(--interactive-primary);
  border-radius: 50%;
  animation: spin 1s linear infinite;
}

@keyframes spin {
  0% { transform: rotate(0deg); }
  100% { transform: rotate(360deg); }
}

Implementation Guidelines

CSS Architecture

  1. Layer Structure: Use CSS layers for better cascade management
  2. Component Isolation: Each component should be self-contained
  3. Token Usage: Always use design tokens instead of hardcoded values
  4. Progressive Enhancement: Ensure components work without JavaScript

JavaScript Integration

  1. Alpine.js Components: Create reusable Alpine.js data functions
  2. HTMX Integration: Design components to work seamlessly with HTMX
  3. Event Communication: Use Alpine.js events for component communication
  4. Performance: Minimize DOM queries and optimize reactivity

Testing Strategy

  1. Visual Regression: Test components across different themes and screen sizes
  2. Accessibility: Automated and manual accessibility testing
  3. Performance: Monitor component rendering performance
  4. Cross-browser: Test in all supported browsers

Documentation Standards

  1. Component Examples: Provide usage examples for each component
  2. Props/Attributes: Document all available options
  3. Accessibility: Document ARIA patterns and keyboard interactions
  4. Browser Support: Specify supported browsers and fallbacks

This component library provides a solid foundation for the ThrillWiki frontend redesign, ensuring consistency, accessibility, and maintainability across all templates and user interfaces.
