Looking for help with my Bootstrap HTML code:
<nav>
<ul>
<li><a>1</a></li>
<li class="active"><a href="#">2</a></li>
<li><a>3</a></li>
</ul>
</nav>
<footer>
back to top
</footer>

In the image provided, the active element 2 covers part of the footer when scrolling. How can I adjust it so that it stays hidden within the footer like the other elements when scrolling down?
