ponsive Horizontal-to-Vertical Menu</h1>

    <p>This example shows how you can build upon Pure Menu and Grid classes. At wide
    window-widths we display a horizontal menu.
    At smaller window-widths,
    we switch to a vertical menu with a toggle control. Grids are used to
    arrange the menus.
    Code reproduced below:</p>

<pre class="code" data-language="html"><code>
      &lt;link rel&#x3D;&quot;stylesheet&quot; href&#x3D;&quot;/css/pure/grids-responsive-min.css&quot;&gt;

      &lt;style&gt;
