• Defining rules that apply to a specific media
• Can be done via a linked style sheet for that media
• Can be done via importing a media-specific stylesheet
• @media rule defines media type or types that rule applies to

<link rel="stylesheet" type="text/css"  href="stylesheet.css"/>
<link rel="stylesheet" type="text/css" media="print" href="print_stylesheet.css"/>

<style type="text/css" media="print">
@import url="print_stylesheet.css" media="print";
...
@media print, handheld { body { font-size: 10pt } }
@media print          { #navigation { display:none } }
@media screen          { body { font-size: 16pt }  }
@media projection
   {
      body { font-size: 16pt } 
      p    { font-size:10pt}
      ...
   }
</style>

• First linked stylesheet applies to all media
• Second stylesheet takes precedence over these rules when printing
