How It Works

Flexible Columns & Rows

Add and remove columns and rows with individual size controls. Choose from fr (fraction), px (pixels), auto, or minmax units for each track. Build any grid structure you need.

Understanding CSS Grid Layout

CSS Grid is a two-dimensional layout system that gives you complete control over rows and columns simultaneously. It was designed specifically for layout, unlike older techniques that repurposed floats or tables. With CSS Grid, you define a grid structure on the container and place items into specific cells or let them auto-flow.

Grid Template Tracks

grid-template-columns and grid-template-rows define the sizes of each column and row in your grid. Tracks can use fixed units (px), flexible fractions (fr), auto sizing, percentages, or the minmax() function. The fr unit is particularly powerful -- it distributes remaining space proportionally, making responsive layouts effortless.

Gap Property

The gap property (also known as grid-gap) controls the spacing between grid tracks. You can set separate values for column-gap and row-gap, or a single value for both. Gap only affects spacing between tracks, not between items and the container edge. This makes it more predictable than margins.

Alignment

justify-items aligns grid items along the inline (row) axis within their cells. align-items aligns items along the block (column) axis. The default value 'stretch' fills the entire cell. Other values (start, center, end) position items within their cells without stretching.

Common Use Cases

Frequently Asked Questions

What is CSS Grid?
CSS Grid is a two-dimensional layout system that lets you create complex layouts with rows and columns simultaneously. Unlike Flexbox (one-dimensional), Grid controls both axes at once, making it ideal for full page layouts, dashboards, galleries, and any design that requires precise row and column control.
What is the difference between CSS Grid and Flexbox?
CSS Grid is two-dimensional (rows and columns), while Flexbox is one-dimensional (row or column). Grid is best for overall page layouts and complex grid structures. Flexbox is best for components and one-directional alignment. They complement each other and are often used together.
What does the fr unit mean in CSS Grid?
The fr (fraction) unit represents a fraction of the available space in the grid container. For example, grid-template-columns: 1fr 2fr creates two columns where the second is twice as wide as the first. The fr unit distributes remaining space after fixed-size tracks (px, auto) are calculated.
How do I create responsive grids with CSS Grid?
Use minmax() with auto-fill or auto-fit for responsive grids. For example: grid-template-columns: repeat(auto-fill, minmax(250px, 1fr)) creates columns that are at least 250px wide and automatically wrap to new rows. Combine with media queries for full responsive control.
What is the gap property in CSS Grid?
The gap property sets the spacing between grid rows and columns. You can set a single value for both (gap: 10px), or separate values for rows and columns (row-gap: 10px; column-gap: 20px). Gap replaces the older grid-gap property and is now also used in Flexbox.
Can I use CSS Grid in all browsers?
Yes, CSS Grid has excellent browser support (97%+ globally). All modern browsers including Chrome, Firefox, Safari, Edge, and their mobile versions fully support CSS Grid. Only Internet Explorer 11 has partial support with an older syntax, but IE11 usage is negligible in 2026.
