Html dom innerheight and innerwidth attributes
The read-only attribute declares the height and width of the document display area of the window, in pixels.
The width and height do not include the height of the menu bar, toolbar, and scroll bar.
IE does not support these attributes. It is replaced by the clientWidth and clientHeight attributes of document.doc umentElement or ducument. body (related to the IE version.
