offsetHeight - offsetWidth Properties
December 9, 2009
Value: integer
Compatibility: WinIE4+, MacIE4+, Moz1+, Safari1+
These properties report the height and width of any element, for a normal block-level element whose height and width are not specified the offsetHeight is determined by the actual height of the content after all text flows. But the offsetWidth always extends the full width of the containing element. For example , a p element consisting of only a few words may report a offsetwidth of many of hundreds of pixels because the p block extends the full width of the body element that represents the containing parent of the p element. To find out the actual width of text within a full-width block-level element wrap the text within an inline element (span) and inspect the offsetWidth property of the span.
