Free CSS Grid Generator

Last updated: October 18, 2026

Quick answer: CSS Grid is the fastest way to build two-dimensional page layouts, but getting the grid-template-columns syntax right by hand is fiddly. This free CSS grid generator lets you build the layout visually — drag the sliders for columns, rows, and gap, click any cell to make an item span multiple columns or rows, start from six battle-tested presets (holy grail, sidebar, dashboard, gallery…) — then copy clean, commented CSS + HTML you can paste straight into your project. Everything runs in your browser; no signup.

Selected: item 1

HTML
Tip: click any cell in the preview, then set its column and row span — the generated CSS updates instantly.

How to Use the CSS Grid Generator

  1. Pick a preset (or set columns, rows, and gap yourself with the sliders).
  2. Choose your track sizing unit — fr for flexible layouts, px for fixed, % for percentage-based.
  3. Click any cell in the preview to select it, then set its column span and row span to stretch it across the grid.
  4. Review the generated CSS and HTML below the preview — they update live as you design.
  5. Copy the code and paste it into your stylesheet and markup. Rename the classes to match your project.

Common Use Cases

CSS Grid Generator vs Alternatives

If you're already deep in a framework's grid system, stay there — consistency beats novelty. For standalone pages, prototypes, and learning, designing the grid visually here and pasting the generated CSS is the fastest honest path to a working layout.

Frequently Asked Questions

How do I create a CSS grid layout?
Three lines: put display: grid on the container, define the tracks with grid-template-columns (e.g. repeat(3, 1fr)), and set the gap. Items flow into cells automatically. This generator writes those lines for you — design visually, copy the CSS, done.
What is the difference between CSS Grid and Flexbox?
Grid is two-dimensional (rows and columns at once); Flexbox is one-dimensional (a row or a column). Rule of thumb: page and section layouts go in Grid, component internals (navbars, button rows, card footers) go in Flexbox. They compose — a grid cell can be a flex container.
What does 1fr mean in CSS Grid?
One fraction of the free space. repeat(3, 1fr) splits the container into three equal columns; 1fr 2fr makes the second column twice as wide as the first. Unlike percentages, fr accounts for gaps automatically, so repeat(12, 1fr) with a 16px gap just works.
How do I make a grid item span multiple columns?
With grid-column: span 2 (or grid-row: span 2 for rows). In this tool, click the cell and set the column span — the spanning rule appears in the generated CSS automatically. Classic uses: a header that spans the full width, a sidebar that spans all rows.
How do I make a CSS grid responsive?
The standard recipe is grid-template-columns: repeat(auto-fit, minmax(250px, 1fr)) — columns appear or collapse as the viewport changes, no media queries. This generator produces fixed track counts, which are the right starting point for intentional layouts; swap in the auto-fit recipe when you want a fluid card grid.
Does CSS Grid work in all browsers?
Yes — every modern browser has shipped Grid unprefixed since 2017 (Chrome 57, Firefox 52, Safari 10.1, Edge 16). Global support is above 98%. If you still support truly ancient browsers, provide a simple stacked fallback — but for virtually every project today, Grid just works.
Should I use CSS Grid or tables for page layout?
Grid, always. Tables are for tabular data, not layout — table layouts break accessibility (screen readers announce them as data), resist responsiveness, and tangle content with presentation. Grid gives you the same visual structure with semantic HTML.
