In this page you can create new classes and choose criteria for them.

Different values can be chosen for criteria, e.g.: "No", "Yes" and "Anything". "No" means that the criterion must not be true in the corresponding class. "Yes" means the opposite. For example, with "Javascript" criterion, "No" value means that only those devices that do not support Javacript can fulfill the class. "Anything" value means that all values will be accepted for that criterion. "Anything" is practical when criteria values are needed to be written in the URL.
