About This Tool

The CSS Grid Layout Generator lets you visually design two-dimensional grid layouts by adjusting grid-template-columns, grid-template-rows, gap properties, and alignment settings. The live preview shows exactly how your grid will look before you write any code.

CSS Grid is the most powerful layout system in CSS, designed for two-dimensional layouts (rows AND columns simultaneously). It complements Flexbox, which handles one-dimensional layouts. This tool generates clean, copy-ready CSS with sensible defaults you can build on.

How to Use

  1. Set grid-template-columns to define column structure. Use preset buttons for common patterns.
  2. Optionally set grid-template-rows (leave as auto for most layouts).
  3. Adjust column-gap and row-gap for spacing.
  4. Use justify-items and align-items to control item placement within cells.
  5. Change item count with the slider to see how the grid responds.
  6. Click Copy to copy the generated CSS.

Use Cases

Front-end developers use CSS Grid for page layouts, dashboard structures, and image galleries. Designers export grid specifications to share with developers as exact CSS. CSS learners use this tool to visually understand how grid properties interact β€” especially the difference between justify-items vs justify-content. Teams building design systems use it to prototype spacing and column patterns.
