A CSS media type names a set of CSS properties. A user agent (such as a wireless device) that claims to support a media type by name must implement all of the properties that apply to that media type. The names chosen for CSS media types reflect target devices for which the relevant properties make sense. Here they are:

Media Name	Target
all	Suitable for all devices.
aural	Intended for speech synthesizers. See the section on aural style sheets for details.
braille	Intended for braille tactile feedback devices.
embossed	Intended for paged braille printers.
handheld	Intended for handheld devices (typically small screen, monochrome, limited bandwidth).
print	Intended for paged, opaque material and for documents viewed on screen in print preview mode.
projection	Intended for projected presentations, for example projectors or print to transparencies.
screen	Intended primarily for color computer screens.
tty	Intended for media using a fixed-pitch character grid, such as teletypes, terminals, or portable devices with limited display capabilities. Authors should not use pixel units with the "tty" media type.
tv	Intended for television-type devices (low resolution, color, limited-scrollability screens, sound available).

Media type names are case-insensitive. Due to rapidly changing technologies, CSS2 does not specify a definitive list of media types that may be values for @media. Future versions of CSS may extend this list. Authors should not rely on media type names that are not yet defined by a CSS specification.
