CSS Grid Builder — Design Grids Visually, Export Clean CSS

Build CSS Grid layouts with live controls for rows, columns, gaps and placement — then copy production-ready grid CSS straight to your clipboard. This free online tool runs entirely in your browser — no data is ever uploaded to a server.

How to Use

1. Set the grid — rows, columns and gap sliders update the preview instantly.

2. Place items — each cell takes your placement rules from the inspector.

3. Tune responsive behavior — adjust template tracks per breakpoint.

4. Export — copy the finished CSS and paste it into any stylesheet.

Example

Choose 3 rows × 4 columns with a 16 px gap, make the center span 2 cells — the exported grid-template-areas is ready to drop into production.
