How can I remove mysterious white-space?

Question

This is a very puzzling problem for me.

If you visit this site on Safari there'll be added an extra 4-500px scrollable whitespace. Obviously it's not supposed to be like this, but I can't seem to grasp what creates this space :S

Inspecting reveals nothing to me, as it seems to be a part of the body, but there's no content in it, so why would it create the space?

If anyone could be able to help me that'd be great :)

Answer 1

Try this for your body on the CSS

body{
    height: auto;
}

Answer 2

Add to your .shiftnav-wrap class

height: auto;

Or add to your wrapper id

#wrapper {
  height: auto;
}

On your style.css
