Jquery Neat Codes request
<p>This is my very first post. I am a freelance front end web developer and I strongly believe it is only fair that I give my clients the best product and service, which neat and clean codes is one of them.</p>

<p>Javascript is a recent technology I acquired and want to get good at. This is the Javascript from <a href="http://oscarinoservices.com/portfolio" rel="nofollow">http://oscarinoservices.com/portfolio</a>. How can I improve it? Please see the source code of the page to see the HTML </p>

<pre><code>&lt;style&gt;
    .twentyall:hover{
        background-image:#000 url(http://oscarinoservices.com/portfolio/themes/bartik/images/menu-glow.png) no-repeat;
    }
    .workall, .workall h1{ display:none; }
&lt;/style&gt;

$(document).ready(function () {
        $('#block-block-1').show(); /* shows the years selector hidden if javascript is disabled */

        $('a#logo').hover(function () {
            $('.workall').hide();
            $('#block-block-9').fadeIn('slow');
        });

        $.each($('.twentyall'), function () {
            $(this).hover(function () {
                $('#block-block-9').hide();
                var id = $(this).attr("id").substring(6);
                $('.workall').hide();
                $('#work20' + id).fadeIn();
            },
            function () {
                $(this).show();
            });
        });

    });
</code></pre>
