class= is a substitute for style=. As you are already using style= I would remove the class= and add any additional coding inside your style=
 * remove class="wikia-infobox"
 * I have added float:right; border:1px solid #B2AF9C; padding:8px; margin: 0 0 .5em 1em; font-size:13px;


 * remove wikia-infobox-header
 * I have added nothing


 * remove wikia-infobox-section-header
 * I have added padding:7px;

I use http://www.quackit.com/css/properties/ for style= coding
