清除浮动
CSS样式中有浮动的情况下,一般都不希望正常的文档流显示的内容被盖住,所以有浮动的情况下,会紧跟着后面加一个div清除浮动。
.clear{
width: 0px;
height: 0px;
clear:both;
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>清除浮动</title>
<style type="text/css">
.div1{
width: 200px;
height: 200px;
background-color: green;
float: left;
}
.div2{
width: 200px;
height: 200px;
background-color: red;
float: left;
}
.div3{
width: 500px;
height: 500px;
background-color: gray;
}
.clear{
width: 0px;
height: 0px;
clear:both;
}
</style>
</head>
<body>
<div class="div1"></div>
<div class="div2"></div>
<div class="clear"></div>
<div class="div3"></div>
</body>
</html>
