我有一个很好的 jquery 向下滑动效果在这里工作：
http://georgedesign.co.uk/test/markupV2/index.html
在“服务”部分或“团队”部分中，您可以单击任何面板并打开“更多信息”框。再次单击该框，它就消失了。
问题是这样的：在 IE(7) 中，名为“关于”的第一个面板的行为与其他面板不同。相反，它滑到父 div 下方并且似乎没有采用“位置：像其他人一样固定'css风格..
这个面板的内容也是不可见的。。
我已经盯着这个问题一两个星期了，我的眼睛正在融化..
我只是不明白为什么它在所有其他浏览器上都能正常工作，而其他面板工作正常，但不是第一个。
如果有人可以快速查看代码并查看我（必须拥有！）错过的内容，我将不胜感激另一双眼睛..！
非常感谢，
G
ps，我确信 JQuery 可以缩短，但我仍在掌握它！;)
如果有帮助，这是代码：

<p>At Athanor we focus on 'value' investing into primarily institutional quality property. We target assets providing long term locational stability, with secure and attractive income returns and which also have the potential for both income and capital growth. Cash forms a significant proportion of our total return expectations.<br>
New opportunities are selected via a combination of research, intelligence and experience.<br>
Our approach is opportunistic both geographically and by property sector, although always with a view to having a balance commensurate with our perception of the risks and rewards associated with those sectors and geographies.<br>
We understand that real estate assets are very responsive to active management. Consequently asset management is a core activity which ensures returns are maximised throughout the life of investments.<br>
Primary geographies – UK and Continental Europe.<br>
Property sectors – all property sectors but primarily retail, logistics/industrial, offices, leisure and residential.</p>
