title: What is a reliable way of doing sidenotes in HTML?
body: <p>I publish a lot of text online, and even wrote a <a href="http://code.google.com/p/typografix" rel="noreferrer">system</a> to format HTML for me. Now, I have a problem: I want to make sidenotes in HTML pages just like books have. Just to explain, sidenotes are those notes in the margins right next to the main body text.</p>
  
  <p>Does anyone know of a good, reliable way to do them -- preferably with plain CSS rather than JavaScript. Thanks!</p>
