CSS Grid Generator

What is a CSS Grid Generator?

A CSS Grid Generator is a visual tool that helps you design and build CSS Grid layouts without writing code manually. Simply input your desired number of columns and rows, set the gap between cells, and preview your layout in real-time. The tool generates clean, production-ready CSS code that you can copy and use immediately in your projects.

How to Use the CSS Grid Generator

1. Set Columns: Enter the number of columns (e.g., "3") or use CSS units (e.g., "1fr 2fr 1fr") to define flexible columns.

2. Set Rows: Specify the number of rows or custom row heights (e.g., "auto 200px").

3. Define Gap: Set the spacing between grid cells (e.g., "15px" or "10px 20px" for different horizontal and vertical gaps).

4. Advanced Spanning: Double-click on grid cells to span them across multiple columns or rows for advanced layouts.

5. Copy Code: Click "Copy CSS" and paste the generated code into your project.

What's the difference between grid-template-columns and grid-template-rows?

grid-template-columns defines how many columns your grid has and their widths. grid-template-rows defines the number of rows and their heights. You can use fixed units (px, em), flexible units (fr), or auto.

What does the "fr" unit mean in CSS Grid?

The "fr" unit stands for "fraction" and represents an equal share of available space. For example, "1fr 2fr 1fr" means the second column gets twice the space of the first and third columns.

How do I make my grid responsive?

Use CSS media queries to change the grid-template-columns value at different screen sizes. For example: @media (max-width: 768px) { .container { grid-template-columns: 1fr; } }

Can I use both "fr" units and "px" together?

Yes! You can mix units. For example, "200px 1fr 200px" creates two fixed-width sidebars with flexible content in the middle.

How does grid-gap work?

grid-gap (or gap) sets the space between grid cells. You can use a single value for uniform spacing or two values (e.g., "10px 20px") for different horizontal and vertical gaps.

Is CSS Grid supported in all browsers?

CSS Grid is supported in all modern browsers including Chrome, Firefox, Safari, and Edge. It's not supported in IE11, so add fallback styles if you need to support older browsers.
