I am in the process of optimizing my Drupal site by removing unnecessary css files.
Running an audit I have found that /misc/ui/jquery.ui.core.css
, /misc/ui/jquery.ui.theme.css
and /misc/ui/jquery.ui.slider.css
are relatively large but are never called.
I have tried removing them in my template.php file with the following but they still remain. How can I unset them?
unset($css[DRUPAL_ROOT.'/misc/ui/jquery.ui.slider.css']);
unset($css[DRUPAL_ROOT.'/misc/ui/jquery.ui.core.css']);
unset($css[DRUPAL_ROOT.'/misc/ui/jquery.ui.theme.css']);
