IntersectionObserverEntry: boundingClientRect property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2019.
TheboundingClientRect read-only property of theIntersectionObserverEntry interface returns aDOMRectReadOnly which in essence describes a rectangle describing the smallest rectangle that contains the entire target element.
Value
ADOMRectReadOnly which describes the smallest rectangle that contains every part of the target element whose intersection change is being described.This value is obtained using the same algorithm asElement.getBoundingClientRect(), so refer to that article for details on precisely what is done to obtain this rectangle and what is and is not included within its bounds.
In the general case, however, it's safe to think of this as the bounds rectangle of the target element.
