title: Make a div background white
body: <p>This may see quite simple, but I'm trying to make a div background white and I can't!</p>
  
  <p>You can see a developing site right here:</p>
  
  <p><a href="http://www.issencial.com/2015/" rel="nofollow">http://www.issencial.com/2015/</a></p>
  
  <p>I have a video background, a div with nav (rt-header) and then a div (rt-feature) that I wanna white so when people scroll down, it overlaps the video one.</p>
  
  <p>I guess it is all set, but only content is white, not the whole div...</p>
  
  <p>Can anyone help me on this?</p>
  
  <p>Many thanks in advance...</p>
