 Abstract: This specification describes an API that can be used to understand the visibility and position of DOM elements ("targets") relative to a containing element or to the top-level viewport ("root"). The position is delivered asynchronously and is useful for understanding the visibility of elements and implementing pre-loading and deferred loading of DOM content.
