slot

A named hole inside a component that an instance projects layout content into — the mechanism behind shared chrome with different bodies.

Example

States

Projected content or fallback. Common to every node: hover / press / focus CSS bags, showWhen / hideWhen, animate.

Stability

This node type is part of the format contract: adding an optional prop is additive; removing the node or narrowing an existing prop is breaking. Prop tables are generated from the schema; this page carries the prose.
