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>
