title: Simple way to show a message bar at the top of a page
body: <p>I would like to implement something like stackoverflow does, the bar at top of the page that shows some message.</p>
  
  <p>I came across this pretty nice effect with a page bounce too: </p>
  
  <p><a href="http://www.slidedeck.com/features/" rel="nofollow">http://www.slidedeck.com/features/</a> (look at the purple top bar coming down)</p>
  
  <p>Is there a simple way to do this? Maybe with only jQuery or other framework?</p>
