CSS实现frameset

首先是HTML代码:
<div id="outer">
  <div id="leftFrame" style="width: 20%;">
    <div style="height: 30%" id="packageListFrame" title="All Packages" >
      Package list goes here
     </div>
    <div style="height: 70%" id="packageFrame" title="All classes and interfaces (except non-static nested types)" >
      Class list goes here
    </div>
  </div>
  <div style="width: 80%;" id="classFrame" title="Package, class and interface descriptions">
   Summary details go here
  </div>
</div>
添加如下样式:
<style type="text/css">
#outer { position: relative; }
#leftFrame {
  position: fixed;
  height: 100%;
  width: 20%;
  top: 0;
}
#classFrame {
  position: absolute;
  left: 21%;
  width: 77%;
}
#packageListFrame{
  position: static;
  height: 200px;
  overflow: scroll; }
#packageFrame {
  position: static;
  height: 70%;
  overflow: scroll;
}
 
</style>
