jQuery is not working. Don’t know why this isn’t working!!!

I can’t figure out why this is not working right now. Can anyone spot an error in the code below?

[code]
<div id=”thinger”>yellow.</div>
<div id=”gizmo”>red.</div>

<script src=”//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js”></script>

<script>
$(function(){

$(“#gizmo”).css(‘color’,’red’);
$(“#thinger”).hide();
});
</script>
[/code]

Also in #JavaScript _↴
