+<h2>stylesheet()</h2>

+<p>The stylesheet() function simplifies the linking of CSS into your document. The arguments are stylesheet(href, optional rel, optional title, optional media).</p>

+<p>For more complete control over the output of the tag, you may want to use the link() function.</p>

+<code>stylesheet('foo.css');<br />

+    // &lt;link href=&quot;http://site.com/foo.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;screen&quot; /&gt;<br />

+<br />

+stylesheet('foo.css', 'alternate stylesheet', 'black and white version', 'screen') .'&lt;br&gt;';<br />

+    // &lt;link href=&quot;http://site.com/foo.css&quot; rel=&quot;alternate stylesheet&quot; type=&quot;text/css&quot; media=&quot;screen&quot; title=&quot;black and white version&quot; /&gt;
