What this calculator does

CSS Grid is a two-dimensional layout system that lets developers define rows and columns to position elements precisely on a web page. This interactive generator allows you to visually design grid layouts by specifying the number of rows and columns, setting track sizes with pixels, fractions, or auto values, defining gaps, and placing items within the grid. It generates clean CSS code including grid-template-columns, grid-template-rows, gap, and grid-area properties. CSS Grid is ideal for page-level layouts, card grids, dashboards, and any design requiring alignment in both dimensions simultaneously, complementing Flexbox which handles one-dimensional flow.

CSS Grid Generator FAQ

When should I use CSS Grid instead of Flexbox?▾
Use CSS Grid for two-dimensional layouts where you need to control both rows and columns simultaneously (page layouts, card grids, dashboards). Use Flexbox for one-dimensional layouts like navigation bars, toolbars, or centering a single element. They work well together — Grid for the page structure, Flexbox for component internals.
What does the fr unit mean in CSS Grid?▾
The fr (fraction) unit distributes available space proportionally. For example, grid-template-columns: 1fr 2fr creates two columns where the second is twice as wide as the first. It is similar to flex-grow but designed specifically for grid tracks.
How do I make a CSS Grid layout responsive without media queries?▾
Use auto-fit or auto-fill with minmax(): grid-template-columns: repeat(auto-fit, minmax(250px, 1fr)). This creates as many columns as fit the container, each at least 250px wide, expanding to fill available space.
