【问题描述】：
我有一个 Asp.Net 创建用户向导并尝试修改和排列它的标签，使其在每个浏览器中看起来都一样。
现在的问题是它在 chrome 中看起来不错，但在 IE9 和 Firefox 中看起来一样。
这是它在 chrome 中的外观：
当我在这里进行检查时，它会在右侧显示元素 .style 属性，该属性具有两个元素，即 position:absolute 和 Z-index:2，这会使所有内容都报废。
IE 和 firefox 的问题来了：
当谈到 Firefox 和 IE 时，它会忽略一切：
我在我的 css 文件中提供了以下属性，如下所示，但这仅适用于 chrome，所以我想知道如何为 IE 和 Firefox 更改它
.signtbl
{
z-index:2;
position:relative !important;
}
这是我的控件的全部代码：

【问题讨论】：
-
您使用
position:absolute的原因是什么？应该没有必要。如果你把它拿出来，那么输入应该与所有浏览器中的标签对齐。 -
绝对位置确实导致了两个元素的崩溃（确实，为什么？）。 DOM 不会考虑这两个项目的宽度，因为它们是绝对位置的。因此，您使用的表格结构会折叠到此。
-
@Deadlykipper-我没有使用任何位置：绝对 element.style 属性本身显示为绝对，是的，这就是我在样式表中所做的，将其称为位置：相对！重要。但这与 Firefox 和 IE 无关
