CSS3简单动画_html/css_WEB-ITnose
css3的动画确实非常绚丽！浏览器兼容性很重要！。
分享两个小动画
<!doctype html><html lang="en"> <head> <meta charset="UTF-8"> <meta name="Generator" content="EditPlus®"> <meta name="Author" content=""> <meta name="Keywords" content=""> <meta name="Description" content=""> <title>C3动画</title> <style> /*****************/ #d1{width:50px;height:50px;background-color:green;float:left; border-radius:50%;} #d2{width:50px;height:50px;background-color:red;float:left; border-radius:50%;position:relative;} @-webkit-keyframes jump{ 0%{transform:rotate(0deg);opacity:1;} 25%{transform:rotate(-10deg);opacity:0.5;} 50%{transform:rotate(0deg);opacity:1;} 75%{transform:rotate(10deg);opacity:0.5;} 100%{transform:rotate(0deg);opacity:1;} } #d1{-webkit-animation:jump 0.3s linear infinite;} @-webkit-keyframes move{ 0%{left:10px;background-color:blue;} 50%{left:800px;background-color:yellow;} 100%{left:10px;background-color:red;} } #d2{-webkit-animation:move 5s linear infinite;} </style> </head> <body> <div id="d1"></div> <div id="d2"></div> </body></html>效果如本博客首页那两个小圆圈！
需要注意的是：
1、在css里创建动画时候要处理兼容性
2、在调用的时候不单要处理兼容性> -webkit-animation: ; -moz-animation: ; -o-animation: ; animation: ;
还要注意animation：animation-name,animation-duration,animation-timing-function,animation-iteration-count
animation-name:是用来定义一个动画的名称
animation-duration是用来指定元素播放动画所持续的时间长，取值:为数值，单位为s （秒.）其默认值为“0”。
animation-timing-function:是指元素根据时间的推进来改变属性值的变换速率，说得简单点就是动画的播放方式.
具有以下六种变换方式：ease;ease-in;ease-in-out;linear;cubic- bezier。就是播放速度~
animation-iteration-count是用来指定元素播放动画的循环次数，其可以取值为数字，其默认值为“1”；infinite为无限次数循环。
