CSS3 - 动画 Animation
动画是进行形状变化和用元素创建动作的过程。
@keyframes
关键帧将控制CSS3中的中间动画步骤。
带左动画的关键帧示例 -
@keyframes animation {
from {background-color: pink;}
to {background-color: green;}
}
div {
width: 100px;
height: 100px;
background-color: red;
animation-name: animation;
animation-duration: 5s;
}
上面的示例显示了具有关键帧语法的动画的高度，宽度，颜色，名称和持续时间。
向左移动动画
<html>
<head>
<style type = "text/css">
h1 {
-moz-animation-duration: 3s;
-webkit-animation-duration: 3s;
-moz-animation-name: slidein;
-webkit-animation-name: slidein;
}
@-moz-keyframes slidein {
from {
margin-left:100%;
width:300%
}
to {
margin-left:0%;
width:100%;
}
}
@-webkit-keyframes slidein {
from {
margin-left:100%;
width:300%
}
to {
margin-left:0%;
width:100%;
}
}
</style>
</head>

<button onclick = "myFunction()">Reload page</button>
