IE 忽略 zIndex
我有这个文本区域（单击特定按钮后会展开），它应该位于该文本输入字段上方。在 FF 和 Chrome 中，它有效。但在 IE(6+7) 中则不然。有谁知道问题出在哪里以及我该如何解决它？
<html>
<head>
<style type="text/css">
.Tbl { width: 100%; }
.Col1 { width: 10%; }
.Col2 { width: 90%; }
.CellTA { background-color: #00F; vertical-align: top; padding: 5px; }
.DivTA { position: relative; }
.DivTA2 { position: absolute; background-color: #FF0; padding: 5px; }
.TA { position: relative; z-Index: 10; height: 50px; width: 200px; }
.CellInp { background-color: #F0F; padding: 5px; }
.DivInp { position: relative; width: 100%; background-color: #0F0; }
.Inp { position: relative; width: 200px; }
</style>
</head>
<body>
<table class="Tbl">
<colgroup>
<col class="Col1" />
<col class="Col2" />
</colgroup>
<tr>
<td>Ref</td>
<td class="CellTA">
<div class="DivTA">
<div class="DivTA2">
<textarea class="TA"></textarea>
</div>
</div>
</td>
</tr>
<tr>
<td>eMail</td>
<td class="CellInp">
<div class="DivInp">
<input type="text" class="Inp">
</div>
</td>
</tr>
</table>
</body>
</html>
提前致谢
编辑：添加填充并更改 DivTA2 的背景颜色
I have this textarea (it's expaned, after clicking on a specific button) which is supposed to be over that text-inputfield. In FF and Chrome, it's working. But not in IE(6+7). Does anyone have a clue, where the problem is and how I could solve it?

Thanks in advance
EDIT: Added padding and changed the background-color of DivTA2

IE 处理
z-index的方式与其他浏览器略有不同。这些博客条目可能对您有帮助：http://annevankesteren.nl/2005/06/z -index
http://brenelz.com /blog/squish-the-internet-explorer-z-index-bug/
简而言之，我认为您可能需要将 z-index 添加到拥有它的父元素。 （我不完全确定将其添加到上一级是否可行——如果这不起作用，您也可以尝试将其添加到祖父母元素中。）
IE treats
z-indexa bit differently than other browsers. These blog entry might be helpful to you:http://annevankesteren.nl/2005/06/z-index

In short, I think you may need to add a z-index to the parent element of the one that has it. (I'm not totally sure if adding it one level up will do -- if that doesn't work you could try adding it to the grandparent element as well.)
