CSS Customization
All the design elements of this wiki have corresponding graphic properties that can be specified in a CSS (Cascading Style Sheet). Not only a single style sheet can be bound to a particular page, but an ordered set of sheets. Each property in one sheet overrides the properties its predecessor sheets, hence the term “cascading”.
The advantage of cascading style sheets is that the design properties are separated from the contents of each page. This way the look and feel of an entire site can be changed just by using a different style sheet without touching the content.
A particular appearance as defined by a particular collection of cascading style sheets is known as a skin. So a different skin literally employs a different look.
The default skin of this wiki is called skittlish. The corresponding CSS file base.css can be found in the pub/skins/skittlish folder.
