之前已经为大家介绍了好多导航菜单。今天为大家再带来一款由css3和jquery实现的卡片折叠式菜单。当菜单关闭的时候，有三维堆叠的效果。我们一起看下效果图：
html代码：
<div id="wrapper">
<h1>
<i class="icon-sort-by-attributes"></i>CSS3 <span>Card Deck Drop Down</span></h1>
<div class="card-drop">
<a class="toggle active" href="#"><i class="icon-camera-retro"></i><span class="label-active">
sridhar</span> </a>
<ul>
<li class="" style="z-index: 6; top: 60px; width: 70%; margin-left: 40px;"><a data-label="Everyting"
href="#"><i class="icon-suitcase"></i>Everyting</a> </li>
<li class="" style="z-index: 5; top: 120px; width: 70%; margin-left: 40px;"><a data-label="Design"
href="#"><i class="icon-magic"></i>Design</a> </li>
<li class="" style="z-index: 4; top: 180px; width: 70%; margin-left: 40px;"><a data-label="UI-UX"
href="#"><i class="icon-bolt"></i>UI-UX</a> </li>
<li class="" style="z-index: 3; top: 240px; width: 70%; margin-left: 40px;"><a data-label="Print"
href="#"><i class="icon-tint"></i>Print</a> </li>
<li class="" style="z-index: 2; top: 300px; width: 70%; margin-left: 40px;"><a data-label="Photography"
href="#"><i class="icon-camera-retro"></i>Phtography</a> </li>
<li class="active" style="z-index: 1; top: 360px; width: 70%; margin-left: 40px;"><a
data-label="sridhar" href="#"><i class="icon-camera-retro"></i>sridhar</a> </li>
</ul>
</div>
<br /> <br /> <br />
<script src="/scripts/2bc/_gg_970_90.js" type="text/javascript"></script>
