title: Margin not working only in Safari (element is at the bottom of the page)
body: <p>Please check the following link in the latest safari: 
  <a href="http://www.grupoguion.com/" rel="noreferrer">http://www.grupoguion.com/</a></p>
  
  <p>The footer is fixed at the bottom and supossed to revealed with the scrolling, so the previous section has a margin-bottom but it doesn't work, only in Safari.
  Everywhere else is ok, even in I.E.
  I tried to add overflow: auto in the page-wrapper, but everything gets weird in all browsers with elements dissapear and appear.
  I also have read that removing height: 100% in the body and html may fix that, but that is not an option for me, because i need the images to fix the browser height.</p>
  
  <p>Does anybody have another possible solution please?</p>
  
  <p>Thank in advance.</p>
