JS get browser height and width values (multi-browser)

In IE:
Document.body.clientWidth ==> Body Object width
Document.body.clientHeight ==> Body Object Height
Document.documentElement.clientWidth ==> Visible Area width
Document.documentElement.clientHeight ==> Visible Area height
In Firefox:
Document.body.clientWidth ==> Body Object width
Document.body.clientHeight ==> Body Object Height
Document.documentElement.clientWidth ==> Visible Area width
Document.documentElement.clientHeight ==> Visible Area height

In Opera:
Document.body.clientWidth ==> Visible Area width
Document.body.clientHeight ==> Visible Area height
Document.documentElement.clientWidth ==> The width of the page object (that is, the body object width plus the margin width)
Document.documentElement.clientHeight ==> Page Object height (i.e. body object height plus margin height)
There is no standard for defining the
IE is:
Document.documentElement.clientWidth ==> 0
Document.documentElement.clientHeight ==> 0
Firefox is:
Document.documentElement.clientWidth ==> Page object width (i.e. body object width plus margin) Document.documentElement.clientHeight = = > Page object height (i.e. body object height plus margin)
Opera is:
Document.documentElement.clientWidth ==> Page object width (i.e. body object width plus margin) Document.documentElement.clientHeight = = > Page object height (i.e. body object height plus margin)

HTML Precise positioning: Scrollleft,scrollwidth,clientwidth,offsetwidth
ScrollHeight: Gets the scroll height of the object.
ScrollLeft: Sets or gets the distance between the left edge of the object and the leftmost of the currently visible content in the window
ScrollTop: Sets or gets the distance between the top of the object and the top of the visible content in the window
ScrollWidth: Gets the scrolling width of the object
Offsetheight: Gets the height of the object relative to the layout or parent coordinates specified by the parent coordinate OffsetParent property
Offsetleft: Gets the calculated left position of the object relative to the layout or the parent coordinate specified by the OffsetParent property
OffsetTop: Gets the computed top position of the object relative to the layout or the parent coordinate specified by the OffsetTop property
Event.clientx horizontal coordinates of relative documents
Event.clienty vertical coordinates of relative documents
Event.offsetx horizontal coordinates relative to the container
Event.offsety the vertical coordinate of the relative container
Document.documentElement.scrollTop The vertical scrolling value
Event.clientx+document.documentelement.scrolltop horizontal coordinates of relative documents + amount of vertical scrolling
