Build CSS Grid layouts visually. Define columns, rows, and gaps with live preview.
CSS Grid is a two-dimensional layout system for the web. Unlike Flexbox (one-dimensional), Grid can handle both rows and columns simultaneously, making it ideal for complex page layouts, card grids, and dashboard designs.
The `fr` unit represents a fraction of the available space. `1fr 2fr` creates two columns where the second is twice as wide as the first. It's similar to flex-grow but specific to CSS Grid.
