CSS Grid Generator
Build CSS Grid layouts visually — set columns, rows, gaps, and alignment — then copy the generated code.
About CSS Grid Generator
CSS Grid is the most powerful layout system in modern CSS, but writing the syntax from scratch — track sizing, gaps, alignment, and placement — is error-prone and slow to iterate on. This generator lets you build the grid visually and produces the container CSS plus matching item HTML, so you start from a working layout instead of a blank file.
Set the number of columns and rows, choose how tracks are sized, and adjust gaps and alignment from controls rather than remembering shorthand. Individual items can be assigned explicit grid-area placements, or left to auto-place for the common case. The tool outputs both the container CSS and matching HTML for a complete starting point.
Front-end developers use it to scaffold card grids, dashboard layouts, and gallery pages before fine-tuning responsive behavior, while designers exploring layout options can compare structures quickly without hand-coding. It's also a handy reference for anyone still learning how tracks, lines, and areas fit together.
How to Use
- Set the number of columns and rows.
- Adjust gaps, alignment, and track sizing.
- Copy the generated grid CSS and HTML.
Example
3 columns, 2 rows, 16px gap grid-template-columns: repeat(3, 1fr); grid-template-rows: repeat(2, 1fr); gap: 16px;
The grid divides the container into three equal columns and two equal rows, with a 16px gutter between cells.
FAQ
What does 1fr mean?
1fr is one fraction of the remaining space, so three 1fr columns split the width into three equal parts.
Can I control which cell an item lands in?
Yes, the tool can emit grid-area placements for individual items, or you can use auto-placement for the common case.
Is the generated HTML included?
Yes, matching HTML for the grid container and items is generated alongside the CSS for a complete starting point.
How does this handle responsive layouts?
The generated CSS targets one container setup, which you then wrap in media queries to switch track counts at different breakpoints. For automatic responsiveness, use auto-fit and minmax tracks so columns reflow with the available width.
What's the difference between grid areas and grid lines?
Grid lines are the numbered lines between tracks; grid areas are named rectangular regions made from them. Area-based placement like grid-area: header is more readable and is what the generator can emit for individual items.
