Beginning XHTML

Known Media Types and Media Type Descriptors

So far, we have used two media types: screen and print. The Cascading Style Sheets Level 2 specification identifies a handful of other media types and qualifies this list as not being considered definitive. With the explosions of Internet appliances, there are certain to be an increasing number of new media types.

As shown in the table above, Cascading Style Sheets Level 2 has ten media types that represent target devices for XHTML content. The names of these media types are called 'media type descriptors'. The media type descriptors are used as values for several case-sensitive attributes described below and must be in lower case.
