Style over Substance, not Style with Substance

No formatting information should be contained within the body of the document, rather, all formatting should be specified through CSS, removing all font, bold, em tags, etc.  Also, this CSS declaration should be removed from each HTML file into a single external file, which is then referenced at the top of each HTML page.  This CSS file can then be cached by the browser, providing an additional boost to the download speed.
