Perfect Combination of CSS Grid and Flexbox

CSS Grid and Flexbox are the two core tools of modern CSS layout. They each have advantages, and using them together reasonably can create a powerful layout system.

Advantages of CSS Grid

CSS Grid is a two-dimensional layout system, suitable for:

  • Complex grid layouts: Such as card grids, dashboards
  • Overall page structure: Header, main, sidebar, footer
  • Irregular layouts: Elements spanning multiple grid units

Advantages of Flexbox

Flexbox is a one-dimensional layout system, suitable for:

  • Component internal layout: Buttons, navigation bars, forms
  • Alignment and distribution: Vertical centering, equal spacing distribution
  • Responsive components: Adaptive content areas

Best Practices

Use Grid for Overall Layout

.container {
  display: grid;
  grid-template-columns: 1fr 3fr 1fr;
  grid-template-rows: auto 1fr auto;
  min-height: 100vh;
}

Use Flexbox for Component Layout

.card {
  display: flex;
  flex-direction: column;
  justify-content: space-between;
}

Summary

Grid and Flexbox are not competitive but complementary. Grid is responsible for overall layout, Flexbox is responsible for component internal layout. Using them together can create a flexible and powerful layout system.
