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 live local preview.
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.
Does it need a server?
No. It runs locally in the browser.
