jquery - jqueryを使用してリンク上にマウスを置いたときにメニューを縮小する方法

Question

以下は私が使用したコードです。ニュースや写真などのタブにカーソルを合わせると、ナビゲーションバーのタブを縮小したいと思います。同じものを実装する方法は？タブにカーソルを合わせている間、他のタブは縮小するはずです。

HTML:

<div id="wrapper">
    <nav id="mainnav">
        <ol>
            <li class="home"><a href="http://www.domain.com"></a></li>
            <li class="news"><a href="http://www.domain.com/p/">News</a></li>
            <li class="photos"><a href="http://www.domain.com/channels/s/">Photos</a> </li>
            <li class="biography"><a href="http://www.domain.com/e/">Biography</a></li>
        </ol>
    </nav>
</div>

CSS:

div#wrapper{
width:990px;
height:auto;
margin:0 auto;

font:15px Arial,Verdana,Helvetica,sans-serif;

}
div#wrapper #mainnav{

アップルのようにやりたい場合は、スローモーションを意味します。jQueryの代わりにCSS3を使用して行うことができます。

CSS3遷移プロパティを使用する

transition: width 2s;
-moz-transition: width 2s; /* Firefox 4 */
-webkit-transition: width 2s; /* Safari and Chrome */
-o-transition: width 2s; /* Opera */

または、apple.comのように必要な場合は、これまたはこれもチェックしてください。
