The easiest markup to include is H1,H2,H3,H4,H5, H6 to instead
of the P element to indicate the major topics in web
resources.  H1-H6 elements can easily be restyled with CSS. 
Screen readers and even main stream broswers like Opera
support navigation to headers.  Using this not only gives
people access to the first main topic, but a way to navigate
quickly to all the main and sub topics on a web resource.
