Does anyone know how to keep the warning from coming up for voice-family (the IE box model hack)? I've seen it done on several sites (simplebits.com is one), but I cannot figure out how he did it. I'm using the same method of calling the external file as he is but I keep getting warnings:

<link rel="stylesheet" media="screen" type="text/css" href="style.css" />
