????????本文将会基于css,实现各种动画效果,接下来会从简单几个例子入手。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>React App</title>
<style>
.circle{
width: 100px;
height: 100px;
border-radius: 50%; // 圆形
background-color: red;
position: absolute; // 绝对定位
transform-origin: right center; // 中心轴
}
@keyframes rotate {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg); // 旋转
}
}
.circle:nth-child(1){
animation: rotate 3s linear infinite;
}
.circle:nth-child(2){
animation: rotate 3s linear 1s infinite;
}
.circle:nth-child(3){
animation: rotate 3s linear 2s infinite;
}
.parent{
position: relative;
}
</style>
</head>
<body>
<div class="parent">
<div class="circle"></div>
<div class="circle"></div>
<div class="circle"></div>
</div>
