CSS3动画实现高亮光弧效果

经常看到图片有一道高亮光弧闪过很炫的效果，其原理很简单可以用css3动画就可以做出这样的效果，用css3动画控制position:absolute的left值，从左向右闪过，这个具体的请看以下代码哈。效果截图如下：

鼠标houver在盒子box上时动画会停止，代码如下：

<!Doctype html>

<html>

<head>

另外一种效果，鼠标houver时效果才出现（触发），代码如下：

<!Doctype html>

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=gbk2312"/>

display: block;

height: 500px;

}

a.floor:hover:before{

-webkit-transition: left 1.5s;

-moz-transition: left 1.5s;

transition: left 1.5s;
