jo_Z13,

Make sure that if you do direct changes in css it will apply entirely to your site.

Here the home page is using featured.tpl from your selected skin folder.

You need to create new css classes and use it while dialogue file is included in featured.tpl

{include file="customer/dialog.tpl" title=$lng.lbl_featured_products content=$smarty.capture.dialog sort=true additional_class="products-dialog dialog-featured-list YOUR ADDITIONAL CLASS"}

Let me know if this help.
