CSS3动画结合js实现3D轮播

昨天晚上有个同行提出要做一个旋转式的3D轮播图(下面统称banner图)。我就为了帮他看了一下相关的技术贴发现符合要求的很少，所以只能自己去动手写了。看到有人写了CSS3立体旋转动画的博客，我就想把这个动画拆分成几个模块来做一个banner效果可不可以？最后自己动手写了一下还是可以的。不过这个banner效果还是存在一些bug，因为不是急用所以我也没有修复。以后有空我会修复的。

html部分代码

  <div class="container">
        <div class="carouse" id="carouse">
            <div class="pic1">1</div>
            <div class="pic2">2</div>
            <div class="pic3">3</div>
            <div class="pic4">4</div>
            <div class="pic5">5</div>
            <div class="pic6">6</div>
            <div class="pic7">7</div>
            <div class="pic8">8</div>
            <div class="pic9">9</div>
        </div>
    </div>
    <div class="btn-group">
        <button id="prev">上一个</button>
        <button id="next">下一个</button>
    </div>
