Any way to add CSS for a single page/node?
This is the sort of thing that I'd do by code, but that's because that's just the way I roll.

In the template.php you will want something like:

function MYTHEME_preprocess_node($vars) {
  if (drupal_get_path_alias("node/{$vars['#node']-&gt;nid}") == 'foo') {
    drupal_add_css(drupal_get_path('theme', 'MYTHEME') . "/css/foo.css");
  }
}


Replace foo with values related to your own code.
