CSS Grid Generator

Configure a bounded CSS Grid visually and copy the matching container and item declarations.

The preview uses synthetic numbered items and accepts no HTML.

Supported grid scope

V1 supports 1–12 columns, rows, and synthetic items; equal fractional, fixed-pixel, or minmax track presets; separate bounded gaps; justify-items and align-items; and one selected item with bounded row and column placement.

Placement that exceeds the configured grid is rejected. This is a focused Grid declaration generator, not a page builder, Flexbox mode, or arbitrary HTML editor.
