如何制作Joomla SEBLOD RTL？

I'm using Joomla 3.1.1. and I came accross a problem while using SEBLOD extention.

Whate PHP code do I have to use (template override) in order to make my website RTL ?

Take this code for example, what do I need to use in order to make it RTL ?

websitename/templates/seb_one/positions/mycontentname/content/mainbody.php:

<?php 
// No Direct Access
defined( '_JEXEC' ) or die;
?>
<p><?php echo $cck->renderField('test'); ?></p>
