- Main Content: 9 columns (right), flexible width
- Footer: Full width, height 80px

**Tablet (768px - 1023px):**
- Container: max-width 100%, padding 24px
- Grid: Single column

Layout Types

• Single Column: Simple vertical layout
• Multi-Column: Sidebar + main content
• Grid Layout: Card grids, image galleries
• Flexbox Layout: Flexible component arrangements
• CSS Grid: Complex two-dimensional layouts
• Fixed Header/Footer: Sticky navigation patterns
• Split Screen: Two-panel layouts
• Dashboard: Multi-widget layouts

Responsive Considerations

• Mobile First: Start with mobile layout
• Breakpoints: Define clear breakpoints (320px, 768px, 1024px, 1920px)
• Adaptive Layouts: How layout changes at each breakpoint
• Content Reflow: How content reorders on smaller screens
• Navigation Patterns: Mobile menu patterns (hamburger, drawer, tabs)

Accessibility Considerations

• Semantic HTML: Use proper HTML5 semantic elements
• Reading Order: Logical content reading order
• Focus Order: Keyboard navigation follows visual order
• Landmarks: Proper use of ARIA landmarks
• Skip Links: Skip navigation links for keyboard users
