CSS Grid vs Flexbox

â–¼

Both CSS Grid and Flexbox are powerful layout systems, but they excel in different scenarios.

CSS Grid:

Grid is a two-dimensional layout system, designed for laying out items in rows and columns simultaneously. It's ideal for:

  • Complex page layouts
  • When you need control over both rows and columns
  • Creating responsive designs with grid template areas

Flexbox:

Flexbox is a one-dimensional layout system, designed for distributing space along a single axis. It's perfect for:

  • Navigation menus
  • Centering content
  • Distributing space between items
  • Creating flexible component layouts

Bottom line: Use Grid for overall page layout, and Flexbox for component-level layouts.
