Does it support intelligent body classes?
It will make your theming life so much easier, it’s absolutely ridiculous …
Read about the WordPress version and the benefits of using this concept for theming purposes here: http://codex.wordpress.org/Template_Tags/body_class
WordPress (2.8+):
<body <?php body_class(); ?>>
Drupal (originally from Zen Theme, since Drupal 6 in core):
<body class="<?php print $body_classes; ?>">
Joomla:
Not available by default, must be built manually in template. The Joomla 1.6 version of the default Milkyway template uses something remotely similar for color and background parameters and template width.
Magento:
<body <?php echo $this->getBodyClass()?'class="'.$this->getBodyClass().'"':'' ?>>
