我正在为共享点制作一个新的母版页，其中包括 3 层。我首先在 php 中创建了页面，它在 Chrome 中完美运行，然后在添加<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">为第一行之后，我终于能够让 z-index 在 IE8 中正常工作。但是，当我随后添加必要的代码以使其成为母版页时，分层不再在 Chrome 或 IE8 中起作用。

代码：-

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<%@ Master Language="C#" %>
<%@ Register tagprefix="SharePoint" namespace="Microsoft.SharePoint.WebControls" assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

事实证明，失败的不是 z-index，而是梯度代码。我现在将它切换为纯色背景颜色，它按预期工作。我会看看我是否可以让渐变代码工作，否则我可能只需要创建渐变图像。
