ResizeObserver extension type

The ResizeObserver interface reports changes to the dimensions of an Element's content or border box, or the bounding box of an SVGElement.

Note: The content box is the box in which content can be placed, meaning the border box minus the padding and border width. The border box encompasses the content, padding, and border. See The box model for further explanation.
