title: HTML / CSS autonumber headings?
body: <p>Is there a way (ideally easy) to make headings and sections autonumber in HTML/CSS?  Perhaps a JS library?</p>
  
  <p>Or is this something that is hard to do in HTML?</p>
  
  <p>I'm looking at an application for a corporate wiki but we want to be able to use heading numbers like we always have in word processors.</p>
