This solution do cover up the scrollbar of body
with the scrollbar of .modal
. So we have no shifting body content.
This solution removes the one property of class .modal_open
and so this class seams obsolete.
May be the setter for this class should be removed in modal.js too.
A demo of this solution is here: http://jsbin.com/oHiPIJi/33
