网站logo扫光效果CSS实现

例如：

<div class="logo">
<a  href="#" rel="home" itemprop="url">
<img src="图片地址" alt="logo" itemprop="logo" width="150" height="50">
</a>
</div>

CSS样式：

/**logo扫光效果CSS**/
#logo:before{  /**根据logo外div样式名称修改before前名称**/
    content:"";
    position: absolute;
    left: -665px; /**第一个数字参数控制扫光速度，数字越大越慢**/
    top: -460px;
    width: 200px;
    height: 10px; /**光标的宽度，可根据实际调整**/
    background-color: rgba(255,255,255,.5);
