Thread:Help talk:Signatures/Linking to a stylesheet within a signature?

Is it possible to link to a css stylesheet from within the signature? If I put "" then it doesn't apply the stylesheet and if I do &lt;link rel="stylesheet" href="mysite.com/wiki_style.css"&gt; then it says "html errors" (I assume because stylesheets are only supposed to be referenced inside of &lt;head&gt;. Any help?
