I have made a jsfiddle of your example and it works ok.
Im linking you also a html file u are using with corrected code.

I moved the script to the head tag.
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function (){
$("#wks").fadeOut(1000,"swing");
});
</script>
</head>
P.s.: If this helped, mark it as the answer. Thanks.
