Situations arise where CSS files or CSS rules are to be added from a module. This recipe covers the steps required to do so.
Getting ready

/**

function mysite_init() {
// The path to the mysite module.
$path = drupal_get_path('module', 'mysite');
// Include mysite.css.
drupal_add_css($path . '/mysite.css');
// Include mysite_special.css, but do not preprocess.
drupal_add_css($path . '/mysite_special.css', 'module', 'all', FALSE);
}
