title: bootstrap modal conflicts with mixitup filterable portfolio
body: <p>I have problems with my filterable portfolio.</p>
  
  <p>The Mixitup filterable portfolio is working fine, but when I add a link to a bootstrap modal and test it all my images in my portfolio shrinks to zero and gets the modal background. But nothing shows.</p>
  
  <p>Whats wrong?</p>
