What is CSS Grid?

CSS Grid Layout is a two-dimensional layout system that arranges content into rows and columns at the same time. Unlike flexbox, which works along a single axis, Grid lets you control both dimensions together, making it ideal for page layouts, image galleries, dashboards, and any design built on a structured grid. It replaced years of float-based and framework-based grid hacks with clean, native CSS.

Key CSS Grid properties

This generator sets the properties you apply to the grid container:

  • display: grid — turns an element into a grid container.
  • grid-template-columns — defines the number and size of columns.
  • grid-template-rows — defines the number and size of rows.
  • column-gap and row-gap — set spacing between tracks.
  • The fr unit — distributes available space in flexible fractions.

How to use the CSS Grid generator

Building a grid takes seconds:

  • Choose how many columns and rows you need.
  • Set the column and row gaps.
  • Pick a sizing mode: equal fr units, auto, or responsive minmax().
  • Copy the generated grid CSS and apply it to your container.

Understanding the fr unit

The fr (fraction) unit is what makes Grid so flexible. Instead of fixed pixels, fr distributes the available space proportionally: grid-template-columns: 1fr 1fr 1fr creates three equal columns that share the row, while 2fr 1fr makes the first column twice as wide as the second. Because it is relative, an fr-based grid adapts smoothly to different container widths without media queries.

Building responsive grids without media queries

One of Grid's most powerful patterns is a responsive layout with no breakpoints at all. Using repeat(auto-fit, minmax(120px, 1fr)), the browser fits as many columns as will comfortably hold your minimum size, then wraps the rest to new rows automatically. Cards reflow from four across on desktop to one on mobile with a single line of CSS — select the responsive minmax option in the generator to see it.

Pro tip

Use Grid for the overall page or section structure — the two-dimensional skeleton — and flexbox for the one-dimensional content inside each cell, like a row of buttons. The two systems complement each other. For single-axis layouts, try our Flexbox Generator.

FAQ

Is this CSS Grid Generator free?
Yes. It is completely free, runs in your browser, and requires no account or sign-up.
What is the difference between CSS Grid and Flexbox?
Grid is two-dimensional and controls rows and columns together, ideal for page layouts. Flexbox is one-dimensional and arranges items in a single row or column. They work well together — Grid for structure, Flexbox for content within cells.
What is the fr unit in CSS Grid?
The fr unit represents a fraction of the available space. For example, 1fr 1fr 1fr creates three equal columns, while 2fr 1fr makes the first column twice as wide as the second. It scales automatically with the container.
How do I make a responsive grid without media queries?
Use grid-template-columns: repeat(auto-fit, minmax(120px, 1fr)). The browser fits as many columns as will hold the minimum width and wraps the rest, so the layout adapts on its own. Choose the responsive option in the generator.
How do I add spacing between grid items?
Use the gap property, or column-gap and row-gap for independent control. This generator lets you set both and includes them in the output CSS.
Can I use CSS Grid for a whole page layout?
Yes. Grid is excellent for full-page layouts with headers, sidebars, main content, and footers, because it controls both rows and columns in one place.
Does CSS Grid work in all browsers?
Yes. CSS Grid is supported in every modern browser, including all current versions of Chrome, Edge, Firefox, and Safari.
