我遇到一个绝对定位的 div 隐藏在 float div 后面的问题。我已经在堆栈上做了很多阅读以获得这个问题的答案，但我没有尝试过，所以我将把源代码放在这里。我不知道我错过了什么。
如果您单击“浏览”文本，我会让 jquery 打开一些选项的菜单。选项位于绝对定位的 div 中，您将在 ie7 模式下看到它们位于其下方的 div 内容后面。我在 IE7 模式下使用 IE9 + IE7 标准来获得此结果。

现在，不要在这个解决方案上引用我的话，因为我只使用 IE7 测试仪，而不是实际的 IE7，但它通常对我有用。目前，我将您的右侧部分背景颜色更改为红色。你可以解决这个问题。
问题在于，您有一个额外的 div 包装您的部分类，其中包含带有“position:relative”样式的内容。 div 未命名，因此不能用样式表引用，所以我删除了它。此外，在第一部分 div 类中，你拼错了 relative 我是如何完全删除它的，因为你不需要它。我最初将每个元素的 z-index 设置为 1，并将 .browsemenu 类上的 z-index 提高到 10。 此外，“Fusce adipi...”开始的段落，在样式引用中随机包含单词 peach 的 div 包装。
我对我所有的编辑都做了评论。 祝你好运，我希望这对你有所帮助。
