Frequently Asked Questions

What is CSS Grid?▾
CSS Grid Layout is a two-dimensional layout system for the web. It lets you lay out items in rows and columns, making it easy to design complex layouts without floats or positioning.
How do grid-template-columns and grid-template-rows work?▾
grid-template-columns defines the number and width of columns, while grid-template-rows defines the number and height of rows. Use fr units for flexible proportions, px for fixed sizes, or auto for content-based sizing.
What is the fr unit?▾
The fr (fraction) unit represents a fraction of the available space in the grid container. For example, 1fr 2fr creates two columns where the second is twice as wide as the first.
How do I span items across multiple cells?▾
Click on a grid cell to start a span, then click an adjacent cell to extend it. The tool generates grid-column and grid-row span rules for the selected item.
Can I use this tool on my phone?▾
Yes, the CSS Grid generator works in any modern mobile browser. Configure your grid layout visually and copy the CSS on any device.
Does the generated CSS include HTML markup?▾
Yes. The tool generates both the CSS grid styles and a matching HTML structure, so you can copy a complete working grid layout directly into your project.
Can I customize the gap between grid cells?▾
Yes. Adjust the row and column gap values to control spacing between grid items. The tool uses the standard CSS gap property, which is supported in all modern browsers.
