Importing an External Style Sheet
Imported style sheets
Instead of linking to an external style sheet, we may import one. Importing an external style sheet is different from linking to an external sheet.
To import a style sheet, we must set the command inside the <style> tag-pair, like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Your document title</title>
<style type="text/css">
@import url(muffett.css);
</style>
</head>
