Best Practices

  1. Mobile-First: Start with mobile styles, enhance for larger screens
  2. Content Breakpoints: Set breakpoints based on content, not devices
  3. Fluid Over Fixed: Use fluid values for typography and spacing
  4. Container Queries: Use for component-level responsiveness
  5. Test Real Devices: Simulators don't catch all issues
  6. Performance: Optimize images, lazy load off-screen content
  7. Touch Targets: Maintain 44x44px minimum on mobile
  8. 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
