# Use CSS Grid for two-dimensional layouts

CSS Grid solves layout problems that previously required JavaScript or complex CSS hacks — aligning items across both axes simultaneously, creating named layout areas, and building responsive grids that adapt to content. Using Flexbox for two-dimensional layouts results in workarounds like fixed widths that break responsiveness.

## Quick Reference

- Use Grid for two-dimensional layouts (rows AND columns); use Flexbox for one-dimensional
- grid-template-areas provides a visual representation of the layout in your CSS
- minmax() and auto-fill/auto-fit create responsive grids without media queries
- Subgrid allows nested elements to align to the parent grid's tracks

## Check

Look for float-based or Flexbox layouts in this CSS that are trying to control both rows and columns — they may be better implemented with CSS Grid.
