title: How does the DiggBar work?
body: <p>How does the DiggBar work?  </p>
  
  <p>I'm trying to make an ASP.NET MVC DiggBar clone just for learning purposes and does anyone have a suggestion on how to specify the url of the content for the lower frame?  How would you go about constructing that in MVC?</p>
  
  <p>Also, I know that it is an iFrame, but how do they position it so regardless of scrolling it stays positioned at the top? Is it CSS magic?</p>

  <p>Edit: I'm not interested in whether or not you like them.  I am not putting one into production and I'm not asking for whether they are good design or not.  I simply ~want~ to make one. </p>
  
  <p>I find the DiggBar useful and I like it. Hell, you can turn it off in two clicks! Similarly, reddit has a reddit bar which is opt-in (probably better approach).</p>
