CSS Grid Generator
Generate CSS Grid layouts visually
About the CSS Grid Generator
CSS Grid is powerful, but writing grid-template-columns: repeat(...) by hand and guessing at gaps slows down quick layout work. CSS Grid Generator gives you simple controls for columns, rows, and gap, then hands back clean, copy-ready CSS alongside a live preview of the layout.
It fits the prototyping moment: roughing out a gallery, a dashboard, or a card layout and wanting the boilerplate CSS without typing it from memory. Adjust the numbers, watch the preview grid update with numbered cells, and paste the generated rules straight into your stylesheet.
How to Use the CSS Grid Generator
- Set the number of columns (1–12) and rows (1–12).
- Enter a gap value — any valid CSS length such as 16px or 1rem.
- Click Generate Grid.
- Check the live preview of the grid, then Copy the generated .grid-container CSS into your stylesheet.
Why Use ToolForge’s CSS Grid Generator
- A live preview renders the actual grid as you configure it, so you see the layout before touching your codebase.
- It outputs clean, standard grid CSS using repeat() and fractional units, ready to paste without editing.
- The gap field accepts any CSS length unit, so you are not locked into pixels.
- It runs entirely in the browser, free and without sign-up.
Frequently Asked Questions
What does the fr unit in the generated CSS mean?
fr stands for "fraction" and distributes available space proportionally. repeat(3, 1fr) creates three columns that each take an equal share of the container's width, which is the most common way to build a responsive, evenly divided grid.
Can I use rem or percentages for the gap?
Yes. The gap field accepts any valid CSS length, so 16px, 1rem, 2%, or similar all work. The value you enter is placed directly into the gap property of the generated CSS.
How do I place items within the grid?
The generated CSS sets up the container and even columns and rows; items flow into cells automatically. To position a specific item across multiple cells, add grid-column or grid-row rules to that item — the generator gives you the container foundation to build on.
Will this grid be responsive on mobile?
A fixed column count stays fixed at every screen size. To make it adapt, wrap the grid in a media query that reduces the column count on narrow screens, or replace repeat(N, 1fr) with repeat(auto-fit, minmax(...)) so columns wrap automatically — both build directly on the CSS this tool generates.
