CSS Grid Template Generator

About this tool

CSS Grid is the right tool when a layout needs coordinated columns and rows. The Grid Template Generator creates either a fixed number of equal columns or a responsive auto-fit layout based on a minimum item width. The live preview shows how the chosen column count and gap affect a realistic set of items.

A responsive pattern such as repeat(auto-fit, minmax(180px, 1fr)) allows cards to wrap according to available space without a media query for every breakpoint. A fixed repeat(3, 1fr) template is more predictable when the design must retain an exact column count. For one-dimensional control bars and alignment, use the Flexbox Generator.

How to use it

1. Choose a fixed column count when the layout must remain structurally consistent.
2. Enable responsive auto-fit when cards should wrap according to their minimum usable width.
3. Set the minimum width based on the actual content rather than an arbitrary device breakpoint.
4. Adjust the gap to create sufficient separation without wasting narrow-screen space.
5. Copy the generated container CSS and test it with the longest real card content.

Useful ways to apply it

• Building responsive tool, product, article or portfolio card grids.
• Creating dashboard panels with equal-width columns.
• Testing the minimum width at which a card remains readable.
• Replacing repetitive breakpoint rules with an auto-fit/minmax pattern.
• Generating a clear base grid before adding named areas or item spans.

Worked example

Responsive auto-fit; min 160px; gap 20px

grid-template-columns: repeat(auto-fit, minmax(min(160px, 100%), 1fr)); gap: 20px;

Edge cases to check

• auto-fit and a fixed repeat count solve different layout problems.
• Minimum track sizes larger than the container can overflow without a protective min() pattern.
• Child min-content sizing can still affect real layouts.

Known limitations

The generator handles a common one-dimensional column template, not named areas, subgrid, masonry proposals or complex row placement.
