CSS Grid Generator — Free Online Tool

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.

Real-World Use Cases for CSS Grid Generator

Creating a Dashboard Grid Layout with 3 Columns and Auto-Rows

Your dashboard needs 3 equal-width columns with 20px gaps. Set columns to 3, rows to 3 (for 9 total cells), and gaps to 20px. Preview shows the 3x3 grid. Copy the generated CSS into your stylesheet. Each cell represents a dashboard widget that you can populate with charts and metrics.

Building a Responsive Photo Gallery Grid

A photo gallery needs 4 columns on desktop with 10px gaps. Set columns to 4, rows to 3 (12 photos), gap to 10px. The preview shows evenly spaced cells. The generated grid-template-columns: repeat(4, 1fr) creates equal-width columns that automatically adjust to the container width.

Learning CSS Grid Layout for a Web Development Course

A student learning CSS Grid experiments with different column and row configurations. Change columns from 2 to 6 and see how the layout changes. Toggle justify-items between center and stretch to understand the alignment behavior. The numbered cells make it clear exactly how many grid areas are created.

Pro Tips for CSS Grid Generator

1Use CSS Grid for overall page layout (header, sidebar, main, footer) and Flexbox for content within each grid cell. They work best together.
2The repeat() function in grid-template-columns (e.g., repeat(3, 1fr)) is the most common pattern for equal-width columns. 1fr means one fraction of the available space.
3For responsive grids without media queries, use auto-fit and minmax: grid-template-columns: repeat(auto-fit, minmax(250px, 1fr)). This creates columns that wrap automatically.
4Numbered grid cells in the preview correspond to the order of your HTML elements. Grid automatically places items in cells following the order of your markup.
