我的 html 页面中有两个部门，它们各自的 css
<html>
<head>
#lowerone
{position:absolute; bottom:25px; right:25px; height:300px; width:300px;}
#upperone
{position:absolute; bottom:25px; right:25px; height:300px; width:300px; overflow:scroll;}
</head>
<body>
<div id="lowerone">
</div>
<div id="upperone">
<img src="/bg.3.jpg" />
</div>
</body>
</html>
但是上面的 div 即 UPPERONE 是不可滚动的。如何使它可滚动？
使用 2 个绝对定位的 div 相互重叠的任何具体原因？并且缺少更多<style>标签...滚动对我有用..
检查下面的代码滚动工作，
<html>
<head>
<style>
#lowerone
{position:absolute; bottom:25px; right:25px; height:250px; width:300px;overflow:scroll;}
#upperone
{position:absolute; bottom:25px; left:25px; height:250px; width:300px; overflow:scroll;}
</style>
</head>
<body>
<div id="lowerone">

</div>
<div id="upperone">
