This example demonstrates a CSS Grid layout using four colored panels arranged in an asymmetric pattern within a full-viewport section. The grid defines named areas—left, center, centerone, and right—to position the crimson divs across rows and columns with gaps. It uses pure CSS grid-template-areas and grid-template-rows to control the layout, while the HTML page includes no JavaScript or external frameworks. The visualization highlights how grid-area assignments and fractional row units (1fr) create a responsive, non-uniform structure.
