add a highlighted frame

[Jenő Kocsi]

listing_details I want to add a frame if the ad is in featured status.

style.css: section # controller_area.featured we have it, but how next?

<section id="controller_area" class="featured">{strip}
{if $pageInfo.Page_type == 'system'}
{include file=$content}
{else}
<div class="content-padding">{$staticContent}</div>
{/if}
{/strip}</section>

I tried to solve it this way, but it's not good because it puts the frame where it shouldn't be.
