jQuery可拖拽3D万花筒旋转特效
这是一个使用了CSS3立体效果的强大特效，本特效使用jQuery跟CSS3 transform来实现在用户鼠标按下拖动时，环形图片墙可以跟随鼠标进行3D旋转动画。效果体验：http://hovertree.com/texiao/jquery/92/进去后可以上下左右的拖动图片。本示例中使用到了CSS3的transform-style 属性，该规定如何在 3D 空间中呈现被嵌套的元素。默认值： flat继承性： no版本： CSS3JavaScript 语法： object.style.transformstyle="preserve-3d"有2个属性值可选择：flat 子元素将不保留其 3D 位置。preserve-3d 子元素将保留其 3D 位置。示例代码如下：
