要使用CSS实现“翻转Y动画”效果，您可以尝试运行以下代码：
<html>
<head>
<style>
.animated {
background-image: url(/css/images/logo.png);
background-repeat: no-repeat;
background-position: left top;
padding-top:95px;
margin-bottom:60px;
-webkit-animation-duration: 1s;
animation-duration: 1s;
-webkit-animation-fill-mode: both;
animation-fill-mode: both;
}
@-webkit-keyframes flipInY {
0% {
-webkit-transform: perspective(400px) rotateY(90deg);
opacity: 0;
}
40% {
-webkit-transform: perspective(400px) rotateY(-10deg);
}
70% {
-webkit-transform: perspective(400px) rotateY(10deg);
}
100% {
-webkit-transform: perspective(400px) rotateY(0deg);
opacity: 1;
}
}
@keyframes flipInY {
0% {
transform: perspective(400px) rotateY(90deg);
opacity: 0;
}
40% {
transform: perspective(400px) rotateY(-10deg);
}
70% {
transform: perspective(400px) rotateY(10deg);
}
100% {
transform: perspective(400px) rotateY(0deg);
opacity: 1;
}
}
.flipInY {
-webkit-backface-visibility: visible !important;
-webkit-animation-name: flipInY;
backface-visibility: visible !important;
animation-name: flipInY;
}
</style>
</head>
<body>
<div id = "animated-example" class = "animated flipInY"></div>
<button onclick = "myFunction()">Reload page</button>
<script>
function myFunction() {
location.reload();
}
</script>
</body>
</html>
