@media

Summary

The @media CSS at-rule associates a set of nested statements, in a CSS block, that is delimited by curly braces, with a condition defined by a media query. The @media at-rule may be used not only at the top level of a CSS, but also inside any CSS conditional-group at-rule.

The @media at-rule can be accessed via the CSS object model interface CSSMediaRule.

Syntax

@media <media types> {
  /* media-specific rules */
}

Media types

Note: Firefox currently only implements the print and screen media types. The FullerScreen extension enables support for the projection media type.

all: Suitable for all devices.
braille: Intended for braille tactile feedback devices.
embossed: Intended for paged braille printers.
handheld: Intended for handheld devices (typically small screen, limited bandwidth).
print: Intended for paged material and for documents viewed on screen in print preview mode. Please consult the section on paged media, and the media section of the Getting Started tutorial for information about formatting issues that are specific to paged media.
projection: Intended for projected presentations, for example projectors. Please consult the section on paged media for information about formatting issues that are specific to paged media.
screen: Intended primarily for color computer screens.
speech: Intended for speech synthesizers. Note: CSS2 had a similar media type called 'aural' for this purpose. See the appendix on aural style sheets for details.
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 groups

Media types are also part of different Media Groups. The following table indicates which types are in which group.

Examples

@media print {
  body { font-size: 10pt }
}
@media screen {
  body { font-size: 13px }
}
@media screen, print {
  body { line-height: 1.2 }
}

Notes

A multimodal media type is still only one media type. The 'tv' media type, for example, is a multimodal media type that renders both visually and aurally to a single canvas.
