Grid Generator

Adjust columns, gap, and item count to generate CSS Grid layout code.

Category: Dev Tools

When to use?

Use it for UIs with a regular cell structure — product card lists, dashboard widgets, image galleries, settings panels. Change columns and gap with a preview and get ready-to-paste CSS Grid code.

How to use

  • Set the column count and gap.
  • Adjust the item count to preview close to the real list size.
  • Check the grid layout in the preview.
  • Copy the generated CSS Grid code.

Input Explanation

Set the number of columns, the gap between columns, and the child item count. A repeat column structure suits even card grids.

Calculation Basis

It builds grid-template-columns: repeat([Columns], 1fr) from the column count and applies the gap, reflecting it in the grid container's inline style.

Usage Examples

  • Draft a grid - Quickly make CSS for repeat-column card lists, galleries, and dashboards.
  • Compare spacing - Change the gap to check that card spacing is not too tight or wide.
  • Aid design review - Paste the generated CSS into docs or review comments to clarify layout intent.

Examples

  • 3 columns, 16px gap → display: grid; grid-template-columns: repeat(3, 1fr); gap: 16px;
  • 4 columns, 24px gap → grid layout code for a product list
  • 2 columns, 12px gap → a 2-column mobile settings card draft

Cautions

  • Generated output is for reference; test carefully before production use.
  • Specific specs or framework-only syntax may cause compatibility issues.

Guides

Core CSS Grid properties

grid-template-columns and grid-template-rows define column and row sizes. The fr unit splits remaining space by ratio.

gap and auto-placement

gap sets cell spacing, and grid-auto-flow sets the auto-placement direction. For complex layouts, name areas with grid-area to use named templates.

Card list layout

Grid fits screens where same-shaped items repeat — product cards, tool lists, image galleries. Decide columns and gap first to quickly compare layout density.

Responsive expansion

Switch the generated repeat columns to an auto-fit + minmax combination to make a responsive grid where column count reduces with screen width.

FAQ

What Grid code does it generate?

A basic grid-template-columns based on repeat(n, minmax(0, 1fr)).

Can I preview the grid?

Yes. Changing columns and gap updates the preview grid instantly.

Can I make a responsive grid?

It is repeat/minmax based, so switching to auto-fit makes a responsive grid where column count adjusts to width.

When do I use Grid vs. Flexbox?

Grid suits card lists/galleries controlling rows and columns; Flexbox is simpler for single-direction alignment.
