CSS Grid Layout is a two-dimensional layout system in CSS that lets you design complex web layouts using rows and columns. It's the most powerful layout tool in modern web design, allowing precise control over both horizontal and vertical positioning of elements.
Grid lines are numbered starting from 1. For a grid with 3 columns, there are 4 column lines (1, 2, 3, 4). An item placed from line 1 to line 4 spans all 3 columns. The same principle applies to row lines.
Flexbox is one-dimensional (row OR column), ideal for components and small-scale layouts. CSS Grid is two-dimensional (rows AND columns), perfect for full-page layouts and complex grid-based designs. They work great together.
The fr unit represents a fraction of the available space. 1fr 2fr 1fr means the middle column gets twice the space of the outer columns. It's flexible and responsive, automatically adjusting to container size.
CSS Grid is supported in all modern browsers (Chrome 57+, Firefox 52+, Safari 10.1+, Edge 16+). For IE11, there's partial support with the -ms- prefix. Global coverage is over 97% as of 2024.
Use auto-fit or auto-fill with minmax() for responsive columns that wrap automatically. For example: grid-template-columns: repeat(auto-fit, minmax(250px, 1fr));. You can also use media queries to change grid layout at breakpoints.
