<h2>Fixed Full-height Side Nav</h2>
<h3>Try to scroll this area, and see how the sidenav sticks to the page</h3>
<p>Notice that this div element has a left margin of 25%. This is because the side navigation is set to 25% width. If you remove the margin, the sidenav will overlay/sit on top of this div.</p>
<p>Also notice that we have set overflow:auto to sidenav. This will add a scrollbar when the sidenav is too long (for example if it has over 50 links inside of it).</p>
