Container block

A box that holds other blocks — the building block behind every starter layout.

A box that holds other blocks — the building block behind every starter layout. Reach for it whenever you need side-by-side content or a visually distinct section — most starter layouts and multi-column designs are just nested containers.

The Container block's Properties Panel with layout mode and spacing controls next to a live Preview pane — The Preview pane on the right shows exactly how the current layout mode and spacing arrange the nested elements.

Settings

Layout (layoutMode) — Column, Row, or Grid: how nested elements are arranged.
Background (background) and Padding (paddingPx).
Gap between elements (gapPx).
Grid columns (gridColumns) — Grid mode only.
Distribute (justify) and Vertical align (alignItems) — how children spread out and cross-align; Row/Grid modes only.
Custom CSS (customStyle) — styles the box itself (background, corners, shadow) — separate from the block-wide Layout → Custom CSS every block has, which positions the box on the page.

An empty container just shows a placeholder note on the canvas until you add something to it.
