jQuery实现可拖拽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。
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: CSS3
JavaScript 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:
