title: Bootstrap affix- keep sidebar within container when position:fixed
body: <p>I'm working on implementing a sticky sidebar using Bootstrap's affix plugin. The sidebar sticks as expected, but i am having trouble keeping the div within a padded container. When the affix class is applied, the sidebar will jump outside of the container and all the way to the right side of my browser window. </p>
  
  <p>Is there a simple way to keep the sidebar in its correct place?</p>
