14.1. Designating Medium-Specific Style Sheets

You can restrict any kind of style sheet to a specific medium, thanks to the mechanisms defined in HTML and CSS. For HTML-based style sheets, you can impose medium restrictions through the media attribute. This works the same for both the link and style elements:

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

<style type="text/css" media="projection">
body {font-family: sans-serif;}
</style>
