CSS Grid Generator

About CSS Grid Generator

CSS Grid Layout is one of the most powerful layout systems in CSS. It allows you to create complex, two-dimensional layouts with rows and columns simultaneously — something that was difficult or impossible with older techniques like floats or even Flexbox alone. This visual CSS Grid generator lets you design grid layouts interactively and export production-ready CSS code.

With this tool, you can configure the number of rows and columns, set gap spacing, choose between equal sizing (1fr), auto-sizing, or minmax() for responsive grids. Click any cell to configure its grid-column and grid-row span, allowing items to span multiple columns or rows. The generated code includes a clean .grid-container class plus individual .grid-item classes for any cells with custom spans.

Use the built-in templates to quickly start with common layout patterns like the Holy Grail layout, sidebar layouts, card grids, and dashboards. CSS Grid is supported by all modern browsers (Chrome, Firefox, Safari, Edge) and is the recommended approach for page-level layouts, while Flexbox remains ideal for one-dimensional component layouts.

FAQ

Q: When should I use CSS Grid vs Flexbox?
A: Use CSS Grid for two-dimensional layouts (rows AND columns simultaneously), like page layouts and complex grids. Use Flexbox for one-dimensional layouts (row OR column), like navigation bars and card rows. They work great together.

Q: What does 1fr mean?
A: The fr unit represents a fraction of the available space. 1fr 1fr 1fr creates three equal columns. 1fr 2fr creates two columns where the second is twice as wide as the first.

Q: What is minmax()?
A: minmax(min, max) defines a size range. minmax(150px, 1fr) means the column will be at least 150px but can grow to fill available space — perfect for responsive designs.

Q: Is CSS Grid supported in all browsers?
A: Yes. CSS Grid is supported in all modern browsers including Chrome, Firefox, Safari, and Edge. It has over 97% global browser support as of 2024.
