title: How do I make a Div that has round corners and a background colour?
body: <p>When I assign "background-color: foo;" to a  element in my CSS file I do not get any colour. What other attributes do i need to declare, I have a absolute width set? Does it need a parent container (it has a basic  as a parent)? What am I missing here?!</p>
  
  <p>Also I'd like to give it round-corners using HTML5. Corners only have to work in Safari as it's for a web app not general consumption.</p>
