Grid Layout Designer

CSS Grid is a powerful layout system that allows you to create complex, responsive layouts with rows and columns. This tool provides a visual interface to design grid layouts without writing code manually, then generates the corresponding CSS and HTML for you to use in your projects.

Grid positions use the format "start / end" where numbers refer to grid lines. For example, "1 / 3" means start at line 1 and end at line 3 (spanning 2 tracks). You can also use "span 2" to span 2 tracks from the start position, or "1 / -1" to span from the first to the last line.

Yes! The tool generates CSS Grid code that is inherently responsive. You can set the container width to "100%" for full responsiveness, and the grid will automatically adjust. For more complex responsive behavior, you can combine the generated code with CSS media queries to change grid properties at different screen sizes.

Preset layouts are common grid patterns like Header+Content+Sidebar, Dashboard Grid, and Card Layout that provide starting points for your designs. Click any preset to instantly apply its configuration and grid items, then customize as needed. These presets demonstrate practical grid layout patterns used in real websites.

Click "Add Cell" to create new grid items. Click on any existing cell in the visual designer to select and edit it. When a cell is selected, you can modify its content, class name, position, and background color in the editor panel below. Use the "Duplicate" button to copy cells or "Delete" to remove them.

Columns and Rows set the number of tracks in your grid. Gap controls spacing between grid items. Width and Height set the overall container dimensions (use %, px, vh, vw, etc.). The Container Class Name sets the CSS class for the main grid container in the generated code.

Absolutely! The tool generates both CSS and HTML code that you can copy or download. The CSS includes all necessary grid properties and item positioning. Simply copy the code and paste it into your project, or download the files and include them in your website.

The visual designer shows a live preview of your grid layout. Grid lines define the tracks, and colored rectangles represent your grid items positioned according to their grid-column and grid-row values. Click items to select them, and their properties will appear in the editor below.

Fr (fractional) units distribute available space proportionally in CSS Grid. While this tool uses "repeat(n, 1fr)" by default for equal column/row sizes, you can modify the generated CSS to use different fr values like "1fr 2fr 1fr" to create columns with 1:2:1 proportions.

Yes! Use overlapping grid positions to create magazine-style layouts. For example, set one item to span multiple columns and rows ("1 / 3, 1 / 4") while placing smaller items in the remaining cells. The visual designer makes it easy to experiment with complex positioning.

The generated CSS Grid code works in all modern browsers (Chrome, Firefox, Safari, Edge) and has been supported since 2017. For older browser support, you may need to add fallback layouts using flexbox or floats, but modern CSS Grid is widely supported and recommended for new projects.

This tool is great for learning CSS Grid through experimentation! Try different configurations, examine the generated code, and see how changes affect the layout. The Help section explains grid positioning syntax, and you can reference CSS Grid documentation for advanced features like grid areas, auto-placement, and alignment properties.
