There is no difference in how graphics and CSS are handled,
so the benefits of reusing a connection is the same.

But there is a difference in number of requests. CSS will typical
be cached by the browser. So number of CSS requests will be a fraction
of number of HTML requests, while pages with lots of graphics
will have many graphics requests per HTML request.
