## media selector

CSS2 defines a media selector for different media types.

### link

Incorporate as part of the "link" element:

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

### @media selector

Or, use "@media" selector in style rule:

    @media print {
      body { font-size: 11pt; }
    }
    @media screen {
      body { font-size: medium; }
    }
    @media print {
      div.navigation {
        display: none;
      }
      hr {
        page-break-after: always;
      }
    }
