Two-D Precision

Control both axes simultaneously. Axonix Grid Architect handles complex spatial relationships that Flexbox can't reach.

Spanning Logic

Create Bento-grids, magazine layouts, and complex dashboards by spanning items across multiple tracks with ease.

Clean Syntax

Every line of CSS is optimized for size and performance. We use the most modern shorthand Grid syntax available today.

Built With Care

“CSS Grid is a two-dimensional layout system that handles both rows and columns simultaneously. This playground uses the latest Grid Level 1 specification with fractional (fr) units and span control.”

Mastering CSS Grid Architect
