This behavior makes adding CSS body classes to your layouts quite simple

Unpack release in the protected/extensions folder.

Then add the behavior to a controller (or even better to your components/Controller.php):

public function behaviors() {
	return array(
              'BodyClassBehavior' => array( 
                     'class' => 'ext.BodyClassBehavior.BodyClassBehavior'
              ),
              ...
	);
}

In your layouts/main.php view, add to your body tag:

</head>
...
<body class="<?php echo $this->getBodyClasses(); ?>">

And you're done!
