实例效果图

实例说明在地图上定位多个不同的点,然后从点中央向外扩散光圈。

实例要点主要考察CSS3中动画的使用

主要代码

        @keyframes myfirst{

            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="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>  

注意事项

1.不同的点通过定位分散排布在地图上

2.每个点内存放着两个不同的隐藏点,隐藏点通过动画延时功能形成点扩散的动态效果

3.点外扩散的扩散圈由隐藏点的阴影构成,然后通过动画一点一点扩大
