使 div 元素匀速向下移动：
<!DOCTYPE html>
<html>
<head>
<style>
div
{
width:100px;
height:100px;
background:red;
position:relative;
animation:mymove 5s infinite;
-moz-animation:mymove 5s infinite; /* Firefox */
-webkit-animation:mymove 5s infinite; /* Safari and Chrome */
-o-animation:mymove 5s infinite; /* Opera */
}
@keyframes mymove
{
from {top:0px;}
to {top:200px;}
}
@-moz-keyframes mymove /* Firefox */
{
from {top:0px;}
to {top:200px;}
}
@-webkit-keyframes mymove /* Safari and Chrome */
{
from {top:0px;}
to {top:200px;}
}
@-o-keyframes mymove /* Opera */
{
from {top:0px;}
to {top:200px;}
}
</style>
</head>
<body>
<p><b>注释：</b>本例在 Internet Explorer 中无效。</p>
<div></div>
</body>
</html>
还可以有变形、缩放、旋转等动画
@keyframes rubberBand {
from {
transform: scale3d(1, 1, 1);
}
30% {
transform: scale3d(1.25, 0.75, 1);
}
40% {
transform: scale3d(0.75, 1.25, 1);
}
50% {
transform: scale3d(1.15, 0.85, 1);
}
65% {
transform: scale3d(.95, 1.05, 1);
}
75% {
transform: scale3d(1.05, .95, 1);
}
to {
transform: scale3d(1, 1, 1);
}
}
