1、首先给浮动的元素加一个父容器
2、给这个父容器添加一个样式 clearfix
clearfix的设置如下:
.clearfix::after{
content: "";
display: block;
clear: both;
}下面是示例：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>清除浮动</title>
<style>
.clearfix::after{
content: "";
display: block;
clear: both;
}
.float{
float: left;
width: 200px;
height: 200px;
}
</style>
</head>
<body>
<div class="clearfix">
<div class="float" style="background-color: pink;"></div>
<div class="float" style="background-color: silver;"></div>
</div>
<div style="width:500px;height: 300px;background-color: orange;">
</div>
</body>
</html>效果：
