<html> ---- position

 position 固定的属性，是全局的。和DIV层次无关。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div style="background-color: aqua">标记1</div>
    <div style="background-color: brown ;position: fixed;
        bottom: 0;right: 0" >标记2</div>
</body>
</html>

结果如下：

 

 

 

 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div style="background-color: aqua ;height: 100px">
        标记1
        <div style="background-color: brown ;"
 >标记2</div>
    </div>
</body>
</html>

 

 

 

 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div style="background-color: aqua ;height: 100px">
        标记1
        <div style="background-color: brown ;position: fixed;right: 0;bottom: 0;"
 >标记2</div>
    </div>
</body>
</html>
