CSS Grid Generator with Preview
Create responsive grid CSS for cards, dashboards, galleries, feature lists, and admin panels. Tune columns, gap, and minmax width with a browser-side preview.
Try a common grid layout
.grid {
display: grid;
grid-template-columns: repeat(3, minmax(180px, 1fr));
gap: 16px;
}CSS layout output is a starter snippet. Test it with your real content, breakpoints, container sizes, and browser support before shipping.
Card layouts
Use it for repeated cards, gallery tiles, product grids, and tool lists.
Responsive panels
Use minmax widths when panels should wrap cleanly across screens.
Example
A 3-column card grid can use repeat(3, minmax(180px, 1fr)) with a 16px gap.
Assumption
Your container has enough width for the chosen min column size and gap.
Limitation
The tool does not generate complex named areas, subgrid, masonry, or framework-specific classes.
Can I use the CSS in React?
Yes. Copy the CSS into a stylesheet or translate the values into your component styles.
Why use minmax?
minmax helps grid columns stay flexible while preserving a useful minimum size.
Is this the same as flexbox?
No. Grid is usually better for two-dimensional rows and columns, while flexbox is often better for one-dimensional alignment.
How is the CSS generated?
It is handled in the browser for this tool based on the current public implementation.
