Linking to an External Style Sheet
Linked style sheets
To link to an external style sheet, we just set a link tag into the head of a document, and write the name of our .css file into it, like this for example:
<!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>
<link href="muffett.css" rel="stylesheet" type="text/css" />
</head>
