Populus provides the ability to use 7 subtle module variations to increase the appeal of your module content and highlight key areas. Through the use of these module suffixes, you can make any module stand out on your site. To use these, just add -hilite1, -hilite2, -hilite3, -hilite4, -hilite5, -hilite6, or -hilite7 in the module class suffix parameter of the module in the Module Manager located in your Joomla administrator.
