Layout

The sheet surface owns the background, shape, elevation, and motion. Default spacing is applied to the headline, content, and actions parts instead of the surface, so custom full-bleed content can opt out by overriding the relevant part padding.

Scrollable content also preserves common descendant visual overflow at its block edges. See Scrollable Content Visual Overflow for the shared surface contract and its customization token.

No Handle

Compact sheet

This sheet hides the drag handle and caps the surface height.
