 create the <code>Resources/Templates/</code> directory inside your book directory. Add a new <code>cartoon.twig</code> template and copy the following Twig code:</p>

<div class="code code">
<pre class="code">&lt;div class=&quot;page:cartoon new-page&quot;&gt;
    &lt;img src=&quot;{{ item.config.image }}&quot; /&gt;
&lt;/div&gt;</pre>
</div>

<p>That's it! You can now use the new <code>cartoon</code> content type in your book and you can create new content types following the same steps explained above.</
