I need change the color of a div when the user go over it.
This script I'm trying does not work. Any idea how to fix it?
    <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.1.js" type="text/javascript"></script>
    <script type="text/javascript">
    $("#arrow-l").hover(
    function() {
        $(this).stop().animate({"background-color": "#999999"}, "slow");
    },
    function() {
        $(this).stop().animate({"background-color": "#BFBFBF"}, "slow");
    });
    </script>
    </head>
...
    <body>
     <div id="arrow-l">prev.</div>
