IE7模态对话框 - 定位错误?

更新
我发现了实际问题 在我的代码中,我引用了叠加层的高度, 在除IE7之外的所有浏览器中,这与窗口大小相同,但在IE7中,这是文档大小。

所以我把它更改为引用窗口大小并且它有效:)。

所以现在我的问题是,为什么IE7会这样做,我是否正确假设IE7是这里的犯规球?

<小时/> 的原始
我正在创建一个模态对话框脚本(供我自己使用)。

代码完美无缺。

Google Chrome, 火狐, IE8 +

然而在IE7中定位完全错误。 Example

这些是我在IE9和IE7中得到的定位值(请记住,这些值小于普通窗口,因为我打开了开发工具。)

  

IE7
  左:367px;
  上:1409px;

     

IE9   左:369.5px;
  上:122.5px;

我需要做些什么来解决这个问题?

CSS
请注意,此css有一些奇怪的规则,例如仅用于测试目的的body标记。
请注意,我知道rgba,box-shadow等在css3无支持浏览器中不起作用,
当对话框正常运行时,我会修复此问题。

尝试删除此行:

   body {
        height: 3000px;
    }

我测试时没有影响FF,反正我真的看不到它的使用。

当你试图让CSS的东西工作时,最好删除不必要的代码,这样你就可以确定问题的根源,除非你认为盒子阴影可能与你的定位问题有关。
