css学习笔记-动画

内容去W3school看,讲的很详细。附上一段笔者的测试代码:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>动画测试</title>
<style>
div {
width: 50px;
height: 50px;
background-color: rebeccapurple;
-webkit-animation:mymove 5s infinite;
-o-animation:mymove 5s infinite;
animation:mymove 5s infinite;
position: relative;
animation-play-state:running;
}
div:hover{
animation-play-state:paused;
}

@keyframes mymove
{
0% {top:0px; left:0px; background:red;}
25% {top:0px; left:100px; background:blue;}
50% {top:100px; left:100px; background:yellow;}
75% {top:100px; left:0px; background:green;}
100% {top:0px; left:0px; background:red;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>

值得一说的是,

1.如果没有写position:relative动画是不会播放的。

2.0%相当于from,100%相当于to
