<h3>Responsive Offcanvas Menu</h3>
<p>You can also hide or show the offcanvas menu on different screen widths, with the .offcanvas-sm|md|lg|xl|xxl classes.</p>
<p>In this example, we hide the offcanvas menu on screens larger than 991px wide. Note that we also hide the button that opens the offcanvas (d-lg-none).</p>
