CSS3-2D变换
举例
.box {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
10.2. 2D缩放
10.3. 2D旋转
10.5. 多重变换
10.6. 变换原点
举例
<head lang="en">
<meta charset="UTF-8">
<title></title>
<style>
.box {
margin: 250px auto;
width: 200px;
height: 200px;
border: 1px solid #000;
transform-origin: 50% 50%;
transform: rotatez(45deg) translatex(100px);
}
</style>
</head>
