*embossed -Intended for paged braille printers.

*print - Used for formatting printed pages.

*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).
 +

===Examples===
 +
You can assign a media type to a CSS declaration with the following syntax
 +
<source lang="css">
 +
@media print {
 +
  body {  
 +
    font-size: 12pt;
 +
    font-color: #000000;
 +
  }
 +
}
 +
</source>
 +
 
 +
To assign more than one declaration style to more than one media type:
 +
 
 +
<source lang="css">
 +
@media print, handheld{
 +
  body {
 +
    font-size: 12pt;
 +
    font-color: #000000;
 +
  }
 +
  img {
 +
    max-width: 100%;
 +
    height: auto;
 +
  }
 +
}
 +
</source>
 +
 
 +
The directives can be used in the main CSS file or in a separate style sheet for a given media type. There must be an include to the CSS file in the templates <head> section (the following is taken from the Joomla! Beez template):
 +
 
 +
<source lang="html4strict">
 +
<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/beez/css/print.css" type="text/css" media="Print" />
 +
</source>

Using CSS style sheets, it is possible to use a set of directives(styles) depending upon the device being used to browse web pages.

Media Types

The recognised media types are:

  • all - Suitable for all devices.
  • aural - For speech synthesizers.
  • braille - Intended for braille tactile feedback devices.
  • embossed -Intended for paged braille printers.
  • handheld - Intended for handheld devices.
  • print - Used for formatting printed pages.
  • 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).

Examples

You can assign a media type to a CSS declaration with the following syntax

@media print {
  body { 
    font-size: 12pt;
    font-color: #000000; 
  }
}

To assign more than one declaration style to more than one media type:

@media print, handheld{
  body { 
    font-size: 12pt;
    font-color: #000000;
  }
  img {
    max-width: 100%;
    height: auto;
  }
}

The directives can be used in the main CSS file or in a separate style sheet for a given media type. There must be an include to the CSS file in the templates <head> section (the following is taken from the Joomla! Beez template):

<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/beez/css/print.css" type="text/css" media="Print" />
