Shadow line items

In CSS it's only possible to add a shadow with Filter, but that only works in IE because it uses DirectX http://msdn.microsoft.com/en-us/library/ms533086(VS.85).aspx.
You can do it with Javascript for example with jQuery: http://eyebulb.com/dropshadow/
I suggest making an images and put that in your CSS and make a div for example exactly under the menu with the shadow background image. But i use images in CSS (PNG or GIF) for this kind of things.
 

>>I suggest making an images and put that in your CSS

So, I add an image to li here?

#navigation ul {
    list-style-type: none;
    width: auto;
    margin: 0;
    padding: 0;
}
#navigation li {
    font-weight:bold;
    float: left;
    width: 70px;
}

Would I basically make an image 70px wide, or would I/could I have that stretch as I wanted?

And then what would I do in the HTML please?


<div id="navigation" align="center" style="width: 701px">
        <ul>
            <li><a href="home.htm">Home</a></li>
            <li><a href="about/about.htm">About</a></li>
            <li><a href="news/news.htm">News</a></li>
            <li><a href="photo_gallery/photo_gallery.htm">Gallery</a></li>
            <li><a href="information_links/information_links.htm">Links</a></li>
            <li><a href="faq/faq.htm">FAQ</a></li>
            <li><a href="contact/contact.htm">Contact</a></li>
            <li><a href="produce/oil_wine.htm">Produce</a></li>
            <li><a href="getting_here/getting_here.htm">Where</a></li>
            <li><a href="customer/customer_quotes.htm">Quotes</a></li>
        </ul>
    </div>

Many thanks!
