css实现3D立方体旋转特效

<div class="rect-wrap">   <!--舞台元素，设置perspective，让其子元素获得透视效果。-->
    <div class="container">   <!-- 容器，设置transform-style: preserve-3d，让其子元素在3D空间呈现-->
        <div class="top slide"></div>   <!--立方体的六个面-->
        <div class="bottom slide"></div>
        <div class="left slide"></div>
        <div class="right slide"></div>
        <div class="front slide"></div>
        <div class="back slide"></div>
    </div>
