CSS Grid vs Flexbox: When to Use Which

CSS Grid and Flexbox are both layout systems, but they solve different problems. Flexbox is one-dimensional — it works along a single axis (row or column). Grid is two-dimensional — it works with both rows and columns at once.

Use Flexbox when:

• Laying out items in a single row or column
• Aligning items inside a container
• Building navigation bars

Use Grid when:

• Building full page layouts
• Creating card grids
• Placing items in specific rows AND columns

In practice, the best approach is to use both together — Grid for the overall page layout and Flexbox for components inside.
