案例实际效果图

案例表明：在地形图上精准定位好几个不一样的点，随后从点中间向扩散光圈。

案例关键点：关键调查CSS3中动漫的应用

关键编码：

<!DOCTYPE html>  
<html lang="en">  
<head>  
    <meta charset="UTF⑻">  
    <title>地形图</title>  
    <style>  
        *{padding:0px;margin: 0px;}  
        .bg{width: 100%;height:770px;position: relative;}  
        .bg img{width: 100%;height: 100%;}  
        .bg .content{width: 748px;height:618px;position: absolute;left: 410px;top: 60px;}

        .bg .content .ten{background: #A2A9B4;position: absolute;left:300px; top:350px;}  
        @keyframes myfirst{  
            20% {transform: scale(2);}  
            40% {transform: scale(3);}  
            60% {transform: scale(4);}  
            80% {transform: scale(5);}  
            100% {transform: scale(6);}  
        }  
    </style>  
</head>  
<body>  
    <div class="bg"><img src="bg.jpg" alt="">  
        <div class="content"><img src="bg1.png" alt="">  
            <div class="one"><p></p><span></span></div>  
            <div class="two"><p></p><span></span></div>  
            <div class="three"><p></p><span></span></div>  
            <div class="four"><p></p><span></span></div>  
            <div class="five"><p></p><span></span></div>  
            <div class="six"><p></p><span></span></div>  
            <div class="seven"><p></p><span></span></div>  
            <div class="eight"><p></p><span></span></div>  
            <div class="nine"><p></p><span></span></div>  
            <div class="ten"><p></p><span></span></div>  
        </div>  
    </div>  
</body>  
</html>

留意事项：

1.不一样的点根据精准定位分散化排布在地形图上

2.每一个点运行内存放着两个不一样的掩藏点，掩藏点根据动漫延时作用产生点外扩散的动态性实际效果

3.点扩散的外扩散圈由掩藏点的黑影组成，随后根据动漫1点1点扩张
