CSS stands for Cascading Style Sheets. Basically has a lot to do with the design of the Wiki, like in the Austin & Ally Wiki, how they added a background to chat, I'm pretty sure the side bar is also added with CSS, and a lot of other design stuff like the main wiki heading, special effects to the wiki, and codes and stuff. But yeah.
