I think the main cost in downloading a (textual) page is generally the TCP 
connection setup and the round-trip GET request for the HTTP transaction, not 
the downloading time. Unless it is cached, an external style sheet requires a 
second HTTP transaction, and hence a second TCP connection setup, whereas 
putting style info into the documents just results in a few hundred extra bytes 
download in an otherwise already-established TCP connection. I think that winds 
up being generally faster.

Actually, you will have more load if you put all the style info in 
the HTML documents. You would have to repeat it over and over again. 
If you have something which applies to paragraphs, you need to repeat 
that style info for each paragraph.

With a style sheet, you send out the style sheets once; any further 
documents using the same style sheet won't need to get the style 
sheet again, it will (usually) be cached by the client or a proxy.

Furthermore, the size of a style sheets is often much, much less 
smaller than a graphic.
