5. CSS Applied Internally

CSS can be applied to a single document via an internalized style sheet. An internal style sheet is defined in the head section of an XHTML document using the <style /> element.

Example 5.1 Applied Internally:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Internalized</title>
    <style type="text/css">
    Selector {
        Property:Value;
    }
    </style>
</head>
    <body>...</body>
</html>
