title: How can I style this div layout with css?
body: <p>I'm trying to get four divs styled as in this image.</p>
  
  <p><img src="https://i.stack.imgur.com/vTEAj.jpg"></p>
  
  <p>I've tried with using <code>float:left</code> but I either get all the divs stuck up on the right side of Div1
  or all of them stuck underneath Div1. I believe I need to do a <code>clear</code> somewhere, is that right?</p>
  
  <p>NB.
  Div2 and Div3 may be different heights.</p>

  Thankyou for the answers so far, they are almost what I needed. To add to the question, is it possible to get this look when the DivContainer doesnt have a fixed width?</p>
