    &lt;/div&gt;
    &lt;div class="card-content"&gt;
        &lt;span class="card-title activator grey-text text-darken-4"&gt;Card Title&lt;i class="material-icons right"&gt;&amp;#xE5D4;&lt;/i&gt;&lt;/span&gt;

What I need? Although material design Icon now work in this example, I need to make "close" button as fab. It means, even <code>card-reveal</code> content scroll down, close button keeps position in <code>card-reveal</code> section and visible.
Is it possible?</p>
