Best Practices
Container:
✓ Use flex-wrap for responsive
✓ Set gap for spacing
✓ Use justify-content/align-items
✓ Consider flex-direction for stacking
Items:
✓ Use flex shorthand
✓ Set min-width: 0 to allow shrinking
✓ Use flex-basis for initial size
✓ Use order sparingly
Layout:
✓ Combine with CSS Grid
✓ Use for component layouts
✓ Test at different sizes
✓ Consider accessibility (order)
Avoid:
✗ Flexbox for grid layouts (use Grid)
✗ Deep flex nesting
✗ Forgetting min-width: 0
✗ Changing order without reason
Conclusion
Flexbox excels at one-dimensional layouts - distributing space and aligning items in rows or columns. Use justify-content for main axis alignment, align-items for cross axis, and flex-grow/shrink/basis for item sizing. The gap property simplifies spacing. Combine with CSS Grid for complex layouts: Grid for overall page structure, Flexbox for component-level alignment.
