CSS与不同浏览器的兼容性

Question

我有一个Asp.Net创建用户向导，并试图在每个浏览器中修改和排列其标签。

现在问题是它在chrome中看起来很好但在IE9和Firefox中看起来相同。

这就是它在chrome中的表现：

当我在这里进行检查时，它会在右侧显示元素.style属性，它有两个元素，即position:absolute和Z-index：2，这使得一切都废弃。

以下是IE和firefox的问题：

说到firefox和IE，它忽略了一切：

我已经在我的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改变它

.signtbl
{
z-index:2;
position:relative !important;
}

这是我控制的整个代码：

  DisableCreatedUser="True" MailDefinition-BodyFileName="~/EmailTemplates/NewAccountTemplate.htm" MailDefinition-From="noreply@imgaid.com" LoginCreatedUser="False" MailDefinition-IsBodyHtml="True" MailDefinition-Priority="High" MailDefinition-Subject="Pending Activation">

为什么不尝试使用表格来控制网格结构中可能经常有用的控件。 这是你可以做的。创建一个你想要放置控件的div 在div中首先创建一个表格结构然后将控制放在个体中  尝试可能会有所帮助
