About this tool

Build grid layouts visually

CSS Grid lays out items in two dimensions — rows and columns at once. Set how many columns and rows you want (or switch on responsive auto-fit), choose a gap, and copy the CSS.

Fixed vs responsive

repeat(3, 1fr) gives exactly three equal columns. Auto-fit with repeat(auto-fit, minmax(200px, 1fr)) fits as many columns as the container allows and wraps on smaller screens — the easiest responsive card grid there is, with no media queries.

Frequently asked questions

Common questions about the CSS Grid Generator.

How do I create a CSS grid?

Set display:grid and grid-template-columns (e.g. repeat(3, 1fr)), then add a gap — this tool generates it for you.

What does 1fr mean?

“1 fraction” — it shares the leftover space equally, so repeat(3, 1fr) makes three equal-width columns.

How do I make a responsive grid?

Use repeat(auto-fit, minmax(200px, 1fr)) — columns fit and wrap automatically with no media queries.

Grid or flexbox — which should I use?

Grid is two-dimensional (rows AND columns); flexbox is one-dimensional (a single row or column). Use grid for page and card layouts.
