CSS Grid Layout is a two-dimensional layout system for the web that lets you arrange content into rows and columns simultaneously. Unlike Flexbox, which is primarily one-dimensional, Grid gives you full control over both axes at once. This CSS Grid generator tool works as a grid layout builder, CSS layout code generator, and visual CSS grid creator for developers and designers who want to understand grid structure before writing it by hand.
Frontend developers use CSS Grid for page-level layout — arranging a header, sidebar, main content area, and footer in a two-dimensional structure that holds its shape across screen sizes. The 1fr unit (fractional unit) divides the available space equally between columns, which is the standard starting point for most grid layouts. The generator's equal columns template produces this immediately.
Designers prototyping card layouts use the responsive minmax(150px, 1fr) template, which uses repeat(auto-fit, ...) to automatically wrap columns to the next row when the viewport narrows. This single CSS rule replaces complex breakpoint-heavy media queries for product card grids, image galleries, and feature sections — the browser handles the column count based on available space.
The live preview in this generator shows exactly how the grid cells will be arranged with the current settings, using distinct colors for each cell so the column and row structure is immediately clear. The generated CSS targets a .grid class — apply this class to your container element and add child elements inside to match the preview layout. All generation runs in your browser with no data sent to any server.
The column-gap and row-gap properties control spacing between cells independently — you might want a wider column gap for readability but a tighter row gap for visual density. Setting both to the same value via the shorthand gap is also common. Adjusting these values in the generator and watching the preview update in real time builds intuition for grid spacing much faster than editing a stylesheet and refreshing a browser manually.
