一下是利用CSS滤镜效果实现渐变翻转的代码，有需要的朋友可以参考下。

<body>
<div>转着好玩</div>

CSS中transform: rotate(<span>360deg</span>);旋转，默认顺时针旋转参数为度数例如：360deg
</span><pre name="code"><span>transition-property:过滤，后面接需要过滤的属性例如：</span><span>width,height,transform,background,font-size,</span><span></span>
<span>transition-duration:后面接相应过滤属性的执行时间。</span><span></span><pre name="code"><span></span><pre name="code"><span></span><pre name="code"><span></span><pre name="code"><span></span><pre name="code"><span>opacity：</span>规定不透明度。从 0.0 （完全透明）到 1.0（完全不透明）。
