Simply click on any grid item in the preview canvas. A properties panel will appear allowing you to easily adjust its Column Span and Row Span, instantly updating the live preview and generated code.

Yes! The generated CSS uses modern properties like fr units and standard gaps, making it fundamentally flexible. You can also define custom min-max templates in the settings.

Yes. The CSS Grid Generator runs entirely in your web browser, meaning it is lightning fast, 100% free, and completely private.

CSS Grid Layout is a two-dimensional layout system for the web. It lets you organize content into columns and rows simultaneously, which makes building complex web layouts much easier than older methods like floats or Flexbox.

Use CSS Grid when you need a two-dimensional layout (both columns and rows simultaneously, like a photo gallery). Use Flexbox for one-dimensional layouts (a single row or a single column, like a navigation bar).

The fr (fractional) unit represents a fraction of the available space in the grid container. If you have three columns set to 1fr 1fr 1fr, they will perfectly share the space into three equal columns.

The gap (or grid-gap) property defines the spacing between your columns and rows. It applies the spacing strictly *between* the items, unlike margins which add spacing to the outside edges as well.

No. CSS Grid has excellent support across all modern browsers (Chrome, Firefox, Safari, Edge). The code generated by this tool uses standard, prefix-free CSS that works everywhere.

Yes! In CSS, any grid item can become a grid container itself. While our visual generator creates a single-level grid, you can easily copy the generated CSS and apply nested grids in your actual codebase.

The tool includes alignment controls for justify-items (horizontal alignment) and align-items (vertical alignment), allowing you to easily center content inside every grid cell.
