I tryed to fix a IE6 double-margin bug (i did everything like in sreencast #23: Conditional Stylesheets) and i did it, but when I tested the site on IE 7, I only saw the white screen. So what has happened there? Can anyone help me? Please look at my site on IE 7 and tell me what i did wrong :( http://liux.net/temp/index.php . Thank you :)
