Quick answer

CSS Grid makes responsive layouts simple without extra frameworks. In short: create; use; add, then complete the remaining steps below.

Step by step

  1. Create a container element and set display: grid.

  2. Use grid-template-columns: repeat(auto-fill, minmax(260px, 1fr)) for flexible columns.

  3. Add gap for consistent spacing.

  4. Place content in child elements: the grid wraps them automatically.

  5. Use media queries for any layout changes at specific widths.

  6. Test at mobile, tablet and desktop sizes in browser developer tools.

  7. Check that text remains readable and nothing scrolls horizontally.
