标题 CSS3动态效果学习笔记
内容
    @keyframe 规定动画
    一般是跟animation一起用
    animation : 规定动画的名字 规定动画的时间 规定动画的速度曲线。
    @keyframe 定义动画的名称{ 动画时长的百分比。{一个或多个合法的 CSS 样式属性} }
    目前大部分浏览器都没有支持@keyframe 和animation;所以要分浏览器书写
    @keyframe
    1.safari和chrome浏览器
    @-webkit-keyframes myfrom{
    from {top:0;}
    to {top:200px;}
    }
    2.Firefox浏览器
    @-moz-keyframes myfrom{
    from {top:0;}
    to {top:200px;}
    }
    3.Opera浏览器
    @-o-keyframes myfrom{
    from {top:0;}
    to {top:200px;}
    }
    animation
    1.safari和chrome浏览器
    @-webkit-animation : myfrom 5s infinite
    2.Firefox浏览器
    @-moz-animation : myfrom 5s infinite
    2.Opera浏览器
    @-o-animation : myfrom 5s infinite
