我正在尝试一个接一个地播放不同的css动画,但我无法弄清楚如何。
基本上我要做的就是播放一个动画,在屏幕上显示15秒,然后播放下一个动画,显示15秒,然后播放到下一个动画,最后一个播放时,它应该从顶部重新开始。
以下是它应该播放的第一个示例,显示15秒,然后转到下一个并执行相同操作。
<style> #animated-example {
width: 300px;
height: 200px;
border: solid 1px #1A7404;
position: absolute;
background-color: #62A80A;
}
.animated {
-webkit-animation-duration: 2s;
animation-duration: 2s;
-webkit-animation-fill-mode: both;
animation-fill-mode: both;
}
@-webkit-keyframes bounceInLeft {
0% {
opacity: 0;
-webkit-transform: translateX(-2000px);
}
60% {
opacity: 1;
-webkit-transform: translateX(30px);
}
80% {
-webkit-transform: translateX(-10px);
}
100% {
-webkit-transform: translateX(0);
}
}
@keyframes bounceInLeft {
0% {
opacity: 0;
transform: translateX(-2000px);
}
60% {
opacity: 1;
transform: translateX(30px);
}
80% {
transform: translateX(-10px);
}
100% {
transform: translateX(0);
}
}
.bounceInLeft {
-webkit-animation-name: bounceInLeft;
animation-name: bounceInLeft;
}
</style>
<img id="animated-example" class="animated bounceInLeft" src="http://webmarketingtoday.com/wp-content/uploads/Screen-Shot-2012-05-24-at-7.31.54-AM-288x216.png">
再运行另一个,显示15秒并继续前进。
<style> #animated-example {
width: 300px;
height: 200px;
border: solid 1px #1A7404;
position: absolute;
background-color: #62A80A;
}
.animated {
-webkit-animation-duration: 1s;
animation-duration: 1s;
-webkit-animation-fill-mode: both;
animation-fill-mode: both;
}
@-webkit-keyframes bounceInDown {
0% {
opacity: 0;
-webkit-transform: translateY(-2000px);
}
60% {
opacity: 1;
-webkit-transform: translateY(30px);
}
80% {
-webkit-transform: translateY(-10px);
}
100% {
-webkit-transform: translateY(0);
}
}
@keyframes bounceInDown {
0% {
opacity: 0;
transform: translateY(-2000px);
}
60% {
opacity: 1;
transform: translateY(30px);
}
80% {
transform: translateY(-10px);
}
100% {
transform: translateY(0);
}
}
.bounceInDown {
-webkit-animation-name: bounceInDown;
animation-name: bounceInDown;
}
</style>

在纯CSS中实现这一目标的唯一方法是同时运行所有动画并进行一些计算:
一旦你在这里看到它就会更清楚:
.animated-example {
width: 300px;
height: 200px;
border: solid 1px #1A7404;
position: absolute;
background-color: #62A80A;
}
.animated {
animation-duration: 20s;
animation-fill-mode: both;
animation-iteration-count: infinite;
}
.bounceInLeft {
-webkit-animation-name: bounceInLeft;
animation-name: bounceInLeft;
}
.bounceInDown {
-webkit-animation-name: bounceInDown;
animation-name: bounceInDown;
}
@keyframes bounceInLeft {
0% {
opacity: 0;
transform: translateX(-2000px);
}
6% {
opacity: 1;
transform: translateX(30px);
}
8% {
transform: translateX(-10px);
}
10% {
transform: translateX(0);
}
40% {
opacity: 1;
transform: translateX(0);
}
42% {
opacity: 1;
transform: translateX(30px);
}
55% {
opacity: 0;
transform: translateX(-2000px);
}
100% {
opacity: 0;
transform: translateX(-2000px);
}
}
@keyframes bounceInDown {
0% {
opacity: 0;
transform: translateY(-2000px);
}
50% {
opacity: 0;
transform: translateY(-2000px);
}
56% {
opacity: 1;
transform: translateY(30px);
}
58% {
transform: translateY(-10px);
}
60% {
transform: translateY(0);
}
90% {
transform: translateY(0);
}
92% {
opacity: 1;
transform: translateY(30px);
}
100% {
opacity: 0;
transform: translateY(-2000px);
}
}

答案 1 :(得分:0)
我通过Noah Addy改编这个概念成功实现了类似的东西:http://digitalfio.github.io/Stagger.css/
您需要稍微处理时间以获得所需的15秒延迟,但除此之外,它应该相当简单。
答案 2 :(得分:0)
animation-delay
会完全按照您要查找的内容而,因为您希望动画在最后一个完成后重复;不幸的是,(目前)没有办法在循环动画的迭代之间指定延迟。
但是,您可以使用一些JavaScript实现您想要做的事情,如下所示。要添加更多动画,只需将其类名添加到代码开头的animations
数组中。
var animations=["bounceInLeft","bounceInDown"],
count=animations.length,
classlist=document.querySelector("img").classList,
holder=document.createElement("div"),
style=window.getComputedStyle(holder),
delay=15,
current,wait,x;
holder.style.display="none";
document.body.appendChild(holder);
animate();
function animate(){
wait=0;
x=0;
while(x<count){
setTimeout(function(a){
classlist.remove(current);
classlist.add(a);
current=a;
},wait*1000,animations[x]);
holder.className=animations[x];
wait+=delay+parseInt(style.getPropertyValue("animation-duration"));
x++;
}
setTimeout(animate,wait*1000);
};
img{
animation-fill-mode:both;
height:200px;
width:300px;
}
.bounceInDown{
animation-duration:1s;
animation-name:bounceInDown;
}
.bounceInLeft{
animation-duration:2s;
animation-name:bounceInLeft;
}
@keyframes bounceInDown{
0%{
opacity:0;
transform:translateY(-2000px);
}
60%{
opacity:1;
transform:translateY(30px);
}
80%{
transform:translateY(-10px);
}
100%{
transform:translateY(0);
}
}
@keyframes bounceInLeft{
0%{
opacity:0;
transform:translateX(-2000px);
}
60%{
opacity:1;
transform:translateX(30px);
}
80%{
transform:translateX(-10px);
}
100%{
transform:translateX(0);
}
}
