What Is CSS Grid Generator?
A free online CSS grid generator. Set the number of columns and rows, adjust gaps, and choose alignment options. See a live preview with numbered cells and copy the CSS code instantly.
CSS Grid is a powerful 2D layout system that lets you arrange content in rows and columns simultaneously, making it ideal for complex page layouts, dashboards, and responsive designs. CSS Grid Generator provides a visual interface for creating grid layouts without writing CSS by hand, with a live preview that updates as you adjust settings.
Set the number of columns (1-12) and rows (1-12) using sliders. Each combination shows an instant preview with numbered cells representing your grid items. The column and row gap controls let you add spacing between grid cells, ranging from 0 to 50 pixels. Adjust these and watch the preview cells space out or tighten up.
The alignment controls set the justify-items (horizontal alignment within each cell) and align-items (vertical alignment within each cell). Options include start, end, center, stretch, and baseline. These properties control how content is positioned within each grid cell — for example, center-aligning text both horizontally and vertically within a grid area for a dashboard card.
The generated CSS output includes the grid-template-columns, grid-template-rows, gap, justify-items, and align-items properties in a copy-ready format. The preview uses numbered cells so you can verify the row and column count matches your intended layout. CSS Grid is supported in all modern browsers and is the recommended approach for 2D page layouts, replacing older methods like float-based layouts and complex flexbox nesting.
