创建一个主盒子命名love,再运用css伪元素::before与::after,在盒子前后增加两个盒子,再利用定位与transform实现功能
具体代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<style>
.love {
position: relative;
margin: 100px auto;
width: 200px;
height: 200px;
transform: scale(.5) rotate(45deg);
background-color: #f00;
animation: nb 2s infinite;
}
.love::before {
content: '';
position: absolute;
width: 200px;
height: 200px;
transform: translateX(-100px);
border-radius: 50%;
background-color: #f00;
}
.love::after {
content: '';
position: absolute;
width: 200px;
height: 200px;
transform: translateY(-100px);
border-radius: 50%;
background-color: #f00;
}
@keyframes nb {
25% {
transform: scale(1) rotate(45deg);
}
50% {
transform: scale(.5) rotate(45deg);
}
75% {
transform: scale(1) rotate(45deg);
}
100% {
transform: scale(.5) rotate(45deg);
}
}
</style>
</head>
<body>
<div class="love"></div>
</body>
