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> <p>Some text..</p> <p>Some text..</p> <p>Some text..</p> <p>Some text..</p> <p>Some text..</p> <p>Some text..</p> <p>Some text..</p> </div> </body> </html>
