<p>ScrollSpy.js highlights page position by applying an 'active' class to the Navigation link within a Bootstrap nav component. It does this by monitoring the #target element of the nav link within the window, waiting for it to reach a given 'Y' position, usually zero.</p>
<p><highlight>This example</highlight> demonstrates some rich, additional features including <strong>animated scrolling</strong>, <strong>focus events</strong> as well as how to offset with a fixed navigation bar.</p>
<p>It also shows how to ensure that the 'last' #target element is able to scroll to the top for a better user experience (UX)</p>

Ensure last #target scrolls to top
</div>
<p>A common problem I see with scrollspy implementations is when the last navigation target doesn't navigation to the top of the screen. This causes issues for scrollspy as well as confusing the user if the target they clicked is half way down the page.</p>
<p>The problem is simple, the document isn't long enough to allow it to scroll to the top.</p>
<p>A simple solution is to dynamically add padding-bottom to the body via JQuery, which increases the height to the pixel perfect minimum. We need to do this both at render/page load and if the window is resized. The below code is a simplified and calculates the height of all sibling elements (after the target) to calculate</p>
