我请求你的帮助!我一直试图解决我的问题 2 天......但没有成功:(

我的问题是关于我的 CSS 菜单。当我在我的 CSS 文件的“nav li:hover ul”部分中指定“position:absolute”时，下拉菜单未在 IE9 上显示。但它在 Chrome、Firefox 和 Safari 中工作...如果我将其更改为“position:relative”，菜单会下降但菜单的所有宽度同时下降...所以子菜单不是 160px宽，它是一个 700px 宽的...

我也试图找出它是否可能来自 NivoSlider，但我没有找到任何解决方案...

这是我的 HTML 代码:

希望你能帮助我!提前谢谢了。夏洛特

PS:这里有两张图片(一张显示在 Chrome 上使用的下拉菜单，另一张显示在 IE 上无法使用的下拉菜单)

最佳答案

您是否检查了绝对定位元素的父元素以确保它是相对定位的？绝对定位的元素将相对于其父容器定位。如果没有指定其他声明，一些浏览器会假定父级是相对定位的。其他浏览器会按字面意思理解您的代码，而不是那么友好。您还可以在 Firefox(或类似工具)中使用 Firebug 来确保元素在页面上的某处“显示”并且只是遇到位置问题吗？如果不是，则可能是悬停目标的呈现没有请求显示菜单。填充，显示: block ； IE 中的宽度/高度声明是此类问题的常见原因。

关于css - 如果导航栏中的绝对位置为 :hover ul，则下拉菜单不会在 IE9 上显示，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12070127/
