title: Changing nav-bar color after scrolling?
body: <p>How can I set the navbar with no background color?</p>
  
  <p>When scrolling down after a div the nav-bar gets a new background-color (the nav-bar should be fixed at top, I use <code>navbar-fixed-top</code> in Bootstrap)</p>
  
  <p>I've tried some tutorials but I didn't succeed.</p>

  I'm talking about that black nav-bar on top.</p>
