利用绝对定位实现的居中
代码如下:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>居中</title>
<style type="text/css">
*{
padding: 0px;
margin: 0px;
}
body {
height: 100%;
overflow: hidden;
}
.father{
position: absolute;
height: 500px;
width: 100%;
background-color:#2AABD2;
}
.children{
position: absolute;
top: 50%;
left: 50%;
background-color: red;
width: 100px;
height: 100px;
margin: -50px 0 0 -50px;
}
</style>
</head>
<body>
<div class="father">
<div class="children">
</div>
</div>
</body>
</html>
效果图如下:
利用flex垂直居中
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>居中</title>
<style type="text/css">
*{
padding: 0px;
margin: 0px;
}
body {
height: 100%;
overflow: hidden;
}
.father{
height: 500px;
width: 100%;
background-color:#2AABD2;
display: flex;
justify-content: center;/*实现水平居中*/
align-items:center; /*实现垂直居中*/
}
.children{
background-color: red;
width: 100px;
height: 100px;
}
</style>
</head>
<body>
<div class="father">
<div class="children">
</div>
</div>
</body>
</html>
效果图如下:
transform+relative实现的居中
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>居中</title>
<style type="text/css">
*{
padding: 0px;
margin: 0px;
}
body {
height: 100%;
overflow: hidden;
}
.father{
position: absolute;
height: 500px;
width: 100%;
background-color:#2AABD2;
}
.children
{
width: 300px;
height: 150px;
background-color: #333333;
position: relative;
top: 50%;
left: 50%;
transform: translateX(-50%) translateY(-50%);
}
</style>
</head>
<body>
<div class="father">
<div class="children">
</div>
</div>
</body>
</html>
效果图如下:
多谢@alexxxcs1提供的另一种方式(不晓得这样能否@到^_^),嘛其实网上实现居中的方式确实很多,互相探讨加深印象。
