Best Practices
- Mobile-First: Start with mobile styles, enhance for larger screens
- Content Breakpoints: Set breakpoints based on content, not devices
- Fluid Over Fixed: Use fluid values for typography and spacing
- Container Queries: Use for component-level responsiveness
- Test Real Devices: Simulators don't catch all issues
- Performance: Optimize images, lazy load off-screen content
- Touch Targets: Maintain 44x44px minimum on mobile
- Logical Properties: Use inline/block for internationalization
Common Issues
- Horizontal Overflow: Content breaking out of viewport
- Fixed Widths: Using px instead of relative units
- Viewport Height: 100vh issues on mobile browsers
- Font Size: Text too small on mobile
- Touch Targets: Buttons too small to tap accurately
- Aspect Ratio: Images squishing or stretching
- Z-Index Stacking: Overlays breaking on different screens
