You can put the above CSS in several different places depending on who you want to see its effects. Placing it in...
 * MediaWiki:Wikia.css on your wiki will make the captions black for everyone who comes to your wiki using the Oasis skin (default Wikia layout). You will need to have admin rights on your wiki before you can edit this page.
 * MediaWiki:Monobook.css on your wiki will make the captions black for everyone who comes to your wiki using the Monobook skin (an alternate Wikia layout). You will need to have admin rights on your wiki before you can edit this page.
 * MediaWiki:Common.css on your wiki will make the captions black for everyone who comes to your wiki regardless of what skin/layout they are using. You will need to have admin rights on your wiki before you can edit this page.
 * Special:MyPage/wikia.css on your wiki will make the captions black for you only on just that wiki.
 * Special:MyPage/global.css on Community Central will make the captions black for you only on every wiki you visit.
