C.Syde's Wiki Preferences CSS

C.Syde's Wiki Preferences CSS is a set of Cascading Style Sheets which can be enabled to add CSS to Special:Preferences, since it is one of the few special pages which is unsupported by local CSS, whether it be site-wide or personal. However, if Stylish is used, the following CSS can be enabled to the page at a personal level. To install the style without manually copying and pasting the code, you will need to install it here.
