I'm using bootstrap v3. When I show a modal with js, it goes well but appear a blank white strip on the very right side of page. After modal hide, this strip disappears. It seems to be a problem caused by css margin-right:15px of "body.modal-open:" in bootstrap css. After I delete the whole code below, it works well. Is that ok to delete it?
body.modal-open,.modal-open .navbar-fixed-top,.modal-open .navbar-fixed-bottom{margin-right:15px}
