About This Tool
CSS Grid Layout is a powerful two-dimensional layout system that lets you control both columns and rows simultaneously. With this visual CSS Grid Builder, you can adjust the number of columns and rows, set the gap between grid items, and fine-tune alignment properties — all in real time. The generated CSS code is ready to copy directly into your stylesheet.
Building responsive grid layouts from scratch can be tedious. This tool eliminates the guesswork by providing a live preview that updates as you tweak each property. Whether you are designing a photo gallery, a dashboard layout, or a product grid, you can iterate quickly and export production-ready CSS with a single click. All settings are stored in the URL so you can share your grid layouts with teammates or bookmark them for later.
Common Use Cases
- Designing responsive product grids, card layouts, and gallery pages for e-commerce and media sites
- Prototyping dashboard layouts with exact column and row configurations before writing any code
- Teaching and learning CSS Grid fundamentals with interactive, real-time visual feedback
- Generating production-ready grid CSS for landing pages, portfolios, and blog archive layouts
- Sharing grid layout presets with teammates via URL parameters for design collaboration
Pro Tips
- Use justify-items to control horizontal alignment inside each cell —
stretch fills the cell width, while center keeps items centered - Pair align-items with justify-items for full two-axis control —
center on both is perfect for evenly spaced icon grids - Save your grid configurations by bookmarking the generated URL — all values (columns, rows, gap, alignment, item count) persist in the query string
- Keep the gap value between 8px and 16px for comfortable visual breathing room in most UI layouts
Frequently Asked Questions
- What is CSS Grid Layout?
- CSS Grid Layout is a two-dimensional layout system for CSS. Unlike flexbox (which is one-dimensional), Grid lets you control both columns and rows at the same time. It uses
grid-template-columns and grid-template-rows to define the track sizes, and gap to control spacing between cells. - What is the difference between justify-items and align-items?
- justify-items controls horizontal alignment along the row axis (left/center/right/stretch). align-items controls vertical alignment along the column axis (top/center/bottom/stretch). Using
stretch for both fills the entire cell, while center for both keeps each item centered within its cell. - How do I create a fixed number of grid items?
- Use the Item Count slider to set how many grid items appear in the preview. Each item displays its index number and takes a unique color from a palette of 12 colors. This is useful for visualizing how your grid behaves with a specific number of children.
- Is this CSS Grid Builder free to use?
- Yes, it is completely free with no sign-up required. Everything runs in your browser — no data is sent to any server. You can share your layouts with teammates via URL, which encodes columns, rows, gap, alignment, and item count settings.
