title: Change bootstrap navbar link color based on position on page
body: <p>I'm slightly confused. I've created multiple page websites before using bootstrap and I'd include the navbar markup on every page and set the current page link to the .active class so that I could access it and highlight it nicely.</p>
  
  <p>I'm now working on a single page website and it has a sticky ("fixed") navbar. I have it set up to scroll using jQuery to specific sections down the page based on that sections ID. However, how to I access the "current" navbar link I'm currently at? </p>
  
  <p>Basically, as I scroll down the page I'll go through all the links and I'd like the link to change color based on what section it is in. Do I need to use jQuery to change the class of the link? Or does bootstrap have something built in for this?</p>
