CSS Grid Generator — Complete Guide & Instructions
MakeCard CSS Grid Generator lets you design a CSS Grid layout visually instead of memorizing grid-template-columns syntax. Set the number of columns and rows, adjust the gap in pixels, choose a column unit (1fr, 100px, or auto), and the preview updates instantly showing every cell in place. When the layout looks right, one click copies clean, ready-to-paste CSS for your stylesheet.
How to Use CSS Grid Generator
- 1 Enter the number of "Columns" (1–8) and "Rows" (1–6) your layout needs.
- 2 Set "Gap (px)" for the spacing between cells — 0 to 40 pixels.
- 3 Choose the "Column unit": 1fr for fluid equal columns, 100px for fixed width, or auto for content-sized.
- 4 Check the live Preview — every numbered cell renders exactly as the CSS will lay out.
- 5 Click "Copy" on the CSS panel and paste the rule into your stylesheet.
Key Features & Capabilities
- Visual controls for columns (up to 8), rows (up to 6), and gap (0–40px).
- Three column sizing modes: fractional 1fr, fixed 100px, and content-based auto.
- Numbered-cell live preview that mirrors the generated grid exactly.
- Clean grid-template-columns / grid-template-rows / gap output.
- One-click copy of the full CSS block.
- No build tools or login — pure in-browser generation.

Practical Everyday Use Cases
- Laying out a photo gallery, card deck, or product grid.
- Prototyping a dashboard with equal or fixed-width columns.
- Learning how grid-template-columns units behave before writing production CSS.
- Quickly generating starter CSS for a responsive section.
Pro Tips for Best Results
- Use 1fr columns for equal-width responsive layouts — they share free space automatically.
- Combine this output with media queries in your own CSS to collapse columns on mobile.
- auto columns shrink-wrap to content — handy for a label + field two-column form.
- Keep the gap consistent with your design system's spacing scale (multiples of 4 or 8).
Common Problems & Solutions
Too many fixed 100px columns can exceed the container width — switch the unit to 1fr so columns share available space instead of overflowing.
The grid only defines track sizes; the parent container still controls overall width. Add width or max-width rules to the grid container in your stylesheet.
Privacy & Security
100% Client-Side Execution
Layout settings and generated CSS never leave your browser — the tool is fully client-side.
Frequently Asked Questions
Everything you need to know about using CSS Grid Generator
fr stands for fraction of free space. grid-template-columns: repeat(3, 1fr) creates three equal columns that stretch to fill the container — the generated code uses this for fluid layouts.
Start with 1fr columns from this generator, then add media queries or auto-fit/minmax() in your CSS to reduce column count on small screens.
Grid is two-dimensional — rows and columns together — ideal for page layouts; flexbox is one-dimensional, best for rows or columns of items. This tool generates grid; use our Flexbox tool for the other.
gap is supported in all modern browsers. If it fails, you may be viewing in a very old browser — older code used grid-gap or margins instead.
