CSS Grid
In plain terms
A CSS layout system for two-dimensional row-and-column layouts.
Going deeper
CSS Grid arranges content into rows and columns simultaneously, enabling complex page layouts with precise control. It handles both axes at once.
Under the hood
Two-dimensional power complements flexbox's single axis; supports named areas and responsive track sizing.
Examples
Page layouts, dashboards, image galleries, magazine-style designs.
Think of it like...
Like a spreadsheet grid you place content into by row and column.
