title: Fancybox Modal Window changing layout in background
body: <p>So, in my website, every time I click on a thumbnail a Bootstrap modal window is launched as it is supposed to, but with a small bug ... all the layout in the background (except the footer) tilts to the right about 20px. When the modal window is closed the layout shifts back to place.</p>
  
  <p>Can someone help me solve this issue or at least give some hints on what can be causing this?</p>
