Frequently Asked Questions

CSS Grid Layout is a two-dimensional layout system for the web. It lets you arrange elements into rows and columns simultaneously, making complex responsive designs easier than ever. With properties like grid-template-columns and grid-template-rows, you define explicit tracks, and then place items anywhere on the grid.

Adjust the sliders and dropdowns on the left panel to modify the grid container properties. You can change the number of columns/rows, gap sizes, alignment, and more. Click any colored box in the preview to customize its column and row span. The generated CSS updates in real time – just copy and paste into your project.

CSS Grid is supported in all modern browsers including Chrome, Firefox, Safari, and Edge. It has over 97% global support. For older browsers like IE11, partial support exists with the -ms- prefix, but we recommend using feature queries or fallback layouts.

Flexbox is one-dimensional (row OR column) and great for components. Grid is two-dimensional (rows AND columns) and perfect for page-level layouts. They can work together! Use Grid for the major layout and Flexbox for aligning items inside grid cells.

The fr unit represents a fraction of the available space in the grid container. For example, 1fr 2fr means the second column gets twice the space of the first. It's extremely useful for flexible, proportional layouts without fixed pixels.
