看了網上那么多手風琴效果的例子，覺得都好繁瑣，看不下去，索性自己寫了一個比較簡單的。

下面是HTML

<div id="accordion"> 
            <ul> 
                <li> 
                    <div class="accordionTitle">1</div> 
                    <div class="accordionMain">222</div> 
                </li> 
                <li> 
                    <div class="accordionTitle">2</div> 
                    <div class="accordionMain accordionActive">222q</div> 
                </li> 
                <li> 
                    <div class="accordionTitle">3</div> 
                    <div class="accordionMain">222dd</div> 
                </li> 
                <li> 
                    <div class="accordionTitle">3</div> 
                </li> 
            </ul> 
        </div>

JS代碼

ul{list-style-type: none;padding: 0px;margin: 0px;} 
        #accordion ul li{float:left;display: inline;} 
        .accordionTitle{width:20px;height:100px;border:1px solid #
000000;background-color:#FFCCFF;writing-mode:lr-tb;margin:1 auto;line-height:24px;float:left;} 
        .accordionMain{margin-left: 22px;display:none;width:100px;height:100px;
background-color: blue;border:1px solid #000000;} 
        .accordionActive{display:block;}

 

直接粘貼復制就可以運行了，不過不要忘記加jQuery包
