What Is a CSS Grid Builder?
A CSS Grid builder is a visual tool for designing two-dimensional layouts using CSS Grid. You define columns, rows, and gaps, then click cells to set span values. The tool generates the corresponding CSS code that you can copy into your project. It eliminates the need to memorize Grid syntax while learning or prototyping layouts.
How to Build a CSS Grid Layout
- Define columns — Enter column definitions using fr, px, or auto (e.g.,
1fr 1fr 1fr) - Define rows — Enter row definitions the same way
- Set gaps — Adjust column and row gap values in pixels
- Click Apply — The preview grid updates to show your layout
- Span cells — Click any cell and set column/row span values
- Copy CSS — Click the copy button to get the generated code

FAQ
What units can I use for columns and rows?
You can use any valid CSS grid track value: fr (fractional units), px (pixels), auto, percentages, minmax(), etc. For example: 1fr 200px auto.
How do I make a cell span multiple columns?
Click a cell in the preview to select it, then set the Column Span value in the panel below. Click 'Set Span' to apply.
Can I create named grid areas?
This tool focuses on track-based Grid definition with span syntax. For named grid-template-areas, you would need to add those manually to the generated CSS.
What happens when spans overlap?
The browser's grid auto-placement algorithm handles overlapping spans. Some cells may shift position. Reset spans if the layout looks unexpected.
Is this tool free?
Yes, completely free with no limits or registration required.
