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：

    
    
    
        body{margin:0;padding:0;}
        .box{width:1000px;margin:200px auto;height:500px;position:relative;text-align:center;}
        .box:hover .rolled{
            -webkit-animation-play-state:paused;
            -moz-animation-play-state:paused;
            -o-animation-play-state:paused;
            -ms-animation-play-state:paused;
        }
        .rolled{
            position:absolute;
            top: 0;
            width:80px;
            height:500px;
            background: -moz-linear-gradient(left,rgba(255,255,255,0)0,rgba(255,255,255,.2)50%,rgba(255,255,255,0)100%);
            background: -webkit-gradient(linear,left top,right top,color-stop(0%,rgba(255,255,255,0)),color-stop(50%,rgba(255,255,255,.2)),color-stop(100%,rgba(255,255,255,0)));
            background: -webkit-linear-gradient(left,rgba(255,255,255,0)0,rgba(255,255,255,.2)50%,rgba(255,255,255,0)100%);
            background: -o-linear-gradient(left,rgba(255,255,255,0)0,rgba(255,255,255,.2)50%,rgba(255,255,255,0)100%);
            -webkit-transform: skewX(-25deg);
            -moz-transform: skewX(-25deg);
            -webkit-animation:rolled 2.5s .2s ease both infinite;
            -moz-animation:rolled 2.5s .2s ease both infinite;
            -o-animation:rolled 2.5s .2s ease both infinite;
            -ms-animation:rolled 2.5s .2s ease both infinite;
            overflow: hidden;
        }
        @-webkit-keyframes rolled{
            0%{left:-150px ;}
            100%{left:920px;}
        }
        @-moz-keyframes rolled{
            0%{left:-150px ;}
            100%{left:920px;}
        }
        @-o-keyframes rolled{
            0%{left:-150px ;}
            100%{left:920px;}
        }
        @-ms-keyframes rolled{
            0%{left:-150px ;}
            100%{left:920px;}
        }
        @keyframes rolled{
            0%{left:-150px ;}
            100%{left:920px;}
        }
