title: Bootstrap Scrollspy & Smooth-Scroll
body: <p>I am having some trouble with scrollspy and smooth scrolling. Please keep in mind that I am new to this thing, just good with my google-fu. :)</p>
  
  <p>The problem is quite frustrating, I 've been trying a whole lot of different solutions the past couple of days but none seems to be working. I am using bootstrap scrollspy and smooth scrolling on single page with 4 sections. Each section has its own glyphicon in the navbar, which should turn pink when that section has been scrolled to. When I click the second icon, it works as intended. When I click on the 3rd one, the 2nd one stays pink, that is active. When I click on the 4th one, the 3rd turns white and the 2nd one stays pink. Furthermore, when scrolling manually, only the first two icons change colour. It is probably easier if you see this behaviour yourselves.</p>
