Help with Jquery Opacity
<p>I have a question in javascript.</p>

<p>Why is this not working:</p>

<pre><code> function scroll_button() { 
        $('div#scrollcase').css('opacity' , 0.3, function() 
        {
            $(this).delay(3500).css('opacity' , 1.0);
        });
    };
</code></pre>

<p>Is a loop.</p>
