Joomla allows different methods to render each module according to the style attribute from the following include:

<jdoc:include type="module" name="right" style="xhtml" />

In templates/system/html/modules.php the system declares the following methods:

• none
• table
• horz
• xhtml
• rounded
• outline

In Addition, professional templates for Joomla usually provide more chrome methods in their templates/the_template/html/modules.php file.

Since version 1.1, Dmod Module Manager allows you to specify your desired style for each Dmod under the "Advanced Parameters".
