本文通过三个实例详细介绍了如何使用CSS @keyframes定义动画效果。包括如何设置不同阶段的元素位置变化，如何同时改变多个CSS属性，以及如何组合多种样式变化实现复杂动画。
亲自试一试 - 实例
实例 1
在一个动画中添加多个 keyframe 选择器：
@keyframes mymove
{
0% {top:0px;}
25% {top:200px;}
50% {top:100px;}
75% {top:200px;}
100% {top:0px;}
}
@-moz-keyframes mymove /* Firefox */
{
0% {top:0px;}
25% {top:200px;}
50% {top:100px;}
75% {top:200px;}
100% {top:0px;}
}
@-webkit-keyframes mymove /* Safari 和 Chrome */
{
0% {top:0px;}
25% {top:200px;}
50% {top:100px;}
75% {top:200px;}
100% {top:0px;}
}
@-o-keyframes mymove /* Opera */
{
0% {top:0px;}
25% {top:200px;}
50% {top:100px;}
75% {top:200px;}
100% {top:0px;}
}
实例 2
在一个动画中改变多个 CSS 样式：
@keyframes mymove
{
0% {top:0px; background:red; width:100px;}
100% {top:200px; background:yellow; width:300px;}
}
@-moz-keyframes mymove /* Firefox */
{
0% {top:0px; background:red; width:100px;}
100% {top:200px; background:yellow; width:300px;}
}
@-webkit-keyframes mymove /* Safari 和 Chrome */
{
0% {top:0px; background:red; width:100px;}
100% {top:200px; background:yellow; width:300px;}
}
@-o-keyframes mymove /* Opera */
{
0% {top:0px; background:red; width:100px;}
100% {top:200px; background:yellow; width:300px;}
}
实例 3
带有多个 CSS 样式的多个 keyframe 选择器：
@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;}
}
@-moz-keyframes mymove /* Firefox */
{
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;}
}
@-webkit-keyframes mymove /* Safari and Chrome */
{
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;}
}
@-o-keyframes mymove /* Opera */
{
0% {top:0px; left:0px; background:red;}
25% {top:0px; left:100px; background:blue;}
50% {top:100px; left:100px; background:yellow;}
