CSS, Cascading Style Sheet, is a style sheet language used for describing the presentation semantics (the look and the format) of a document written in markup language. This may be hard for beginners to understand, let me put it this way, a link is presented in color blue before being clicked, but turns red and underlined when you move your mouse over it, this is called a style. By the use of CSS, display attributes of all elements, such as layout, color and font can be controlled uniformly.
