I tested the code and it works fine, although you have a line "document"instead documentand an ancient attribute languagein the script tag ...
Use type="text/javascript"a script tag. You can simply send the function to the jQuery object as a shortcut to use the ready-made function:
<script type="text/javascript">
$(function(){
$('#bling').hide();
});
</script>
However, since this is not the code that is the problem, there is something else on your page.
