Re: [Public WebGL] Mysterious extra padding below canvas

When I have other elements on a page together with a canvas, in order to compute an ideal canvas size, I need to query, or compute, things like the margin, border and padding heights of elements, particularly the body element. I have not so far found any way through the DOM to obtain this information.  The queries I've found return (content area + padding) or (content area + padding + border). I have found no query whose result is influenced by the margin nor any to tell me the padding.

Style queries return empty strings unless a style is actually set on the element so are useless for elements having default settings.

Can anyone suggest a way to determine this information?
