Grid

Summary

A two-dimensional layout system for arranging items into rows and columns simultaneously — ideal for page layouts and complex component grids. Grid lets you define explicit tracks as well as flexible layouts, making it especially useful when relationships between rows and columns matter at the same time.

• 1Rebuild a page layout (header/sidebar/content/footer) using CSS Grid. Validate your understanding by applying it in a small practical example.
• 2Practice `grid-template-columns`, `grid-template-areas` and `fr` units. Test it with at least one normal case and one edge case so you can explain the behavior confidently.
• 3Learn when Grid beats Flexbox (2D layouts) and vice versa (1D layouts).
