✓ Test at various container sizes
✓ Provide sensible defaults
Performance:
✓ Avoid excessive nesting
✓ Use containment appropriately
✓ Test with real content
✓ Profile rendering performance
Compatibility:
✓ Provide fallbacks for older browsers
✓ Use @supports for feature detection
✓ Consider progressive enhancement
✓ Test across browsers
Conclusion
Container queries enable truly component-based responsive design. Use size queries for layout changes, style queries for theming, and container query units for fluid sizing. Always provide fallbacks and test thoroughly across container sizes.
