Click through position-area values and watch where an anchored element lands around its anchor.

A small interactive demo for the position-area property in CSS anchor positioning. You click one of the position areas around an anchor and a tooltip moves there, with the matching position-area declaration shown for copying.
Toggles let you switch to logical values and show the inset-modified containing block, which helps you see why an element lands where it does.
It covers position-area only; it does not cover anchor(), position-try fallbacks or other parts of the spec. In browsers without anchor positioning, the page says it is for demonstration only.
