How it works
Pick a preset, or start from the default 3×3 grid.
Adjust the column and row counts, gaps, and alignment.
Select an item to place it with a custom column or row span, then copy the CSS.
Frequently asked questions
No. The grid and the generated CSS are built entirely in your browser.
A custom placement past your explicit column or row count creates an extra implicit track automatically - that is valid CSS, not a bug.
justify-items positions content inside each cell. justify-content positions the whole set of tracks inside the container - you only see a difference when the tracks don't fill the container.
Yes, and that's correct. A grid's column axis follows the page direction, so column 1 renders on the opposite physical side under RTL, with no extra code - this tool shows real CSS Grid behavior, not a left-to-right approximation.
