Thread:Project:Support desk/Linking to common.css/reply (3)

Hi Bawolff, yes, I loaded both Mediawiki:Common.css and Mediawiki:Cavendish.css into the website but they don't seem to be functioning. For example:
 * body.page-Why_people_resist_buying_life_insurance h1.firstHeading { display: none; }

at Mediawiki:Cavendish.css doesn't seem to function, as can be seen on this page.

Cavendish.css, however, appears inside the cavendish folder, something that is not similarly found inside the Monobook folder. Could this be a possible reason that since Cavendish.css already appears at the back-end, it should not appear again at the front-end? I also understand that some skins do not interact with Mediawiki:Common.css.
