Split pane

Two places with a divider you can move: dragged one to one, it snaps to the default size or shut on the part spring; keys step it on settle.

Use it for

  • A list beside its details, a canvas beside an inspector, an editor over its preview: two places whose balance people change.

Don't use it for

  • A sidebar that only opens and closes (use the sidebar place), or content that should reflow instead (use a responsive layout).
