This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The IntersectionObserverEntry
interface's read-only boundingClientRect
property returns a DOMRectReadOnly
which in essence describes a rectangle describing the smallest rectangle that contains the entire target element.
Syntax
var boundsRect =
IntersectionObserverEntry.boundingClientRect;
Value
A DOMRectReadOnly
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 as Element.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 simply think of this as the bounds rectangle of the target element.
