CSS Flexbox vs. Grid
The definitive guide on when to use CSS Flexbox versus CSS Grid for your layouts.
A
CSS Flexbox
Pros
- ✓ One-dimensional: perfect for rows or columns
- ✓ Excellent for component-level alignment
- ✓ Great browser support
- ✓ Intuitive for navigation bars and button groups
Cons
- ✗ Not ideal for two-dimensional layouts
- ✗ Complex nested layouts get messy
- ✗ Items can overflow or wrap unexpectedly
BEST FOR
Navigation bars, button groups, centering content, card rows, toolbars, any single-axis layout
B
CSS Grid
Pros
- ✓ Two-dimensional: controls both rows AND columns
- ✓ Ideal for page-level layouts
- ✓ Named grid areas for readability
- ✓ Alignment is explicit and predictable
Cons
- ✗ More complex syntax
- ✗ Slightly harder to understand at first
- ✗ Overkill for simple one-axis layouts
BEST FOR
Page layouts, dashboard grids, photo galleries, any layout requiring both row and column control
Verdict
Flexbox is for components (one direction). Grid is for layouts (two directions). They are complementary — use Grid for the overall page structure and Flexbox for components within those areas.
