CSS Grid Layout is a two-dimensional layout system that allows you to create complex web layouts with rows and columns simultaneously. Unlike Flexbox (one-dimensional), Grid handles both axes at once, making it ideal for page-level layouts and magazine-style designs.
CSS Grid was created to solve the challenges of web page layout. Before Grid, developers used floats, positioning, tables, and Flexbox — all of which have limitations for two-dimensional layouts. Grid introduces grid containers, grid items, explicit grid lines, named areas, and powerful alignment properties for both rows and columns.
You define a grid container with display: grid, then specify column and row tracks using grid-template-columns and grid-template-rows. Items are placed using grid-column and grid-row or named grid areas. The grid auto-placement algorithm fills items into cells, and the fr unit distributes remaining space proportionally. Features like gap, minmax(), and auto-fit enable responsive layouts without media queries.
Grid is two-dimensional (rows and columns), Flexbox is one-dimensional (row OR column). Use Grid for page layouts and Flexbox for component-level alignment of items in a single direction.
Yes. CSS Grid is supported in all modern browsers (Chrome, Firefox, Safari, Edge) since 2017. Internet Explorer has partial support with an older implementation.
Yes, they work well together. Use Grid for the overall page layout and Flexbox for alignment within grid items or components.
