title: CSS to keep element at "fixed" position on screen
body: <p>I'm looking for a trick to create a "fixed" HTML object on the browser screen using CSS. I want it to stay in the same position all the time, even when the user scrolls through the document. I'm not sure what the proper term for this is.</p>
  
  <p>It would be like the chat button on Facebook or the Feedback button that is on some websites that follows you throughout the page.</p>
  
  <p>In my situation, I want to keep a div at the absolute bottom-right corner of the screen at all times. Sample CSS appreciated.</p>
