Module chrome can be specific to a particular theme and can be added easily. To do so, add folder named "html" to your theme folder. Inside that, add a file named "modules.php".
Here's an example of a simple module chrome definition:
function modChrome_simple( $module, &$params, &$attribs ) { echo '<div class="simple">'; if ($module->showtitle) { echo '<h3>' .$module->title .'</h3>'; } echo $module->content; echo '</div>'; }
You can then use the module chrome in a theme like so:
<?php modules('left', 'simple', '', ''); ?>
