{{APIRef("Intersection Observer API")}}
The IntersectionObserverEntry interface of the Intersection Observer API describes the intersection between the target element and its root container at a specific moment of transition.
Instances of IntersectionObserverEntry are delivered to an {{domxref("IntersectionObserver")}} callback in its entries parameter; otherwise, these objects can only be obtained by calling {{domxref("IntersectionObserver.takeRecords()")}}.
IntersectionObserverEntry object.intersectionRect to the boundingClientRect.true if the target element intersects with the intersection observer's root. If this is true, then, the IntersectionObserverEntry describes a transition into a state of intersection; if it's false, then you know the transition is from intersecting to not-intersecting.IntersectionObserver's time origin.This interface has no methods.
