title: Navbar and Container
body: <p>I have a navbar in a container-class-div because i want in desktop-view the nav not touching the edge of monitor, but in mobile-view it should stretch to the sides.</p>
  
  <p>I have tried two containers, one as container and the other as container-fluid and making them disappear with the hidden-xx classes, but this isn't working.</p>
  
  <p>Anyone an Idea how can I solve that problem?</p>
