CSS Grid vs Flexbox: When to Use Which?
Confused about whether to use Grid or Flexbox? Here is a simple rule of thumb: Flexbox for one dimension, Grid for two dimensions.
The Core Difference
Flexbox is designed for layout in one dimension - either a row OR a column. Grid is designed for two-dimensional layout - rows AND columns at the same time.
When to use Flexbox
- Aligning items inside a navigation bar.
- Centering a div vertically and horizontally.
- Linear lists of items.
When to use Grid
- Defining the overall page layout (Header, Sidebar, Main, Footer).
- Complex image galleries.
- Overlapping elements.
