CSS Grid Builder
CSSVisual CSS grid layout builder with live preview and presets
Set column and row counts visually and watch the preview update, or drag grid items across cells to define `grid-column`/`grid-row` spans for specific placement, a much faster feedback loop than writing grid CSS blind and reloading to check. `minmax()` and `fr` units are both supported and reflected live as the container resizes, and output can use either numeric line placement or named `grid-template-areas` if that reads more clearly for your layout. Presets for common patterns like a holy-grail layout or a card grid give a faster starting point than building from an empty grid. CSS Grid itself has broad modern browser support, but there's no fallback generated for very old browsers like IE11 if that's still a real constraint. It's built for prototyping and common layouts: highly dynamic, JS-driven grid behavior still needs to be hand-coded.
How to use CSS Grid Builder
- 1.Set the number of columns and rows visually and watch the grid preview update to design a layout without writing CSS by hand.
- 2.Drag grid items across cells to define `grid-column` and `grid-row` spans for a specific item placement.
- 3.Start from a preset (like a holy-grail layout or card grid) and tweak it instead of building a grid from scratch.
