Ready — try the example.
States and behavior
Bounded pane widths, pointer capture, keyboard focus and canceled drag.
Keyboard
Tab reaches the divider; Left/Right adjusts 5%; Home/End reaches limits; Escape cancels an active drag.
Scope and adaptation
The divider is not a scroll bar. Touch resizing uses pointer events; minimum widths keep both panes reachable.
