Introduction
Wikipedia:Help:Cascading style sheets may be the best way to introduce yourself to CSS. This wiki does not use CSS excessively, however there are some things which do use it.

Client-Sided Custom Stylesheets
To use a modified stylesheet, it is best to do it client-sided, that way you can view the different styles even when logged off. Internet Explorer for Windows: Tools > Internet Options > Accessibility > Check "Format documents using my style sheet" > Click 'Browse' and search for your CSS file, then click OK to confirm. Mozilla Firefox, Netscape (6.0 and later) and Mozilla: Create your customized CSS file and name it "userContent.css", place it in the Chrome folder stored in 'Profiles' of Mozilla's application data. Restart the browser. Opera 8 and later: Tools > Preferences > Advanced > Content > Style options > Choose, and find your custom CSS.

Server-Sided Custom Stylesheets
Though the wiki's CSS usage tries to avoid site styling conflicts, other sites may make use the same classes, signing up a user account (if you don't already have one) and putting it in your user CSS file will remove any issues with cross-site styling. As a downside, it will only take effect when you are signed on.
