IE中奇怪的z-index或链接问题

[英]Weird z-index or link issue in IE

 原文  2012-03-05 04:23:18  7   2    html/ css/ z-index

问题描述

我正在为我的学校编程一个网站，我想使背景中的角色具有悬停效果。 当您将鼠标悬停在大多数浏览器中的这些字符上时，会弹出一个对话框，说明它们是谁。 在Internet Explorer以外的所有浏览器中，此功能都可以正常工作。 在IE中，链接的一小部分是可单击的，但其余部分则不是。 我不确定这是否与类似的z-index有关，因为它的z-index设置得很高。

这是CSS：

感谢您的帮助，因为我花了很长时间尝试解决这个问题，并且我相信我们都同意IE对于Web开发人员非常令人沮丧。

我不确定哪个IE能满足您的需要-但在至少IE7中，我已经遇到了绝对定位链接的奇怪悬停状态问题。

即使您给它提供display：block，“ clickable”或“ rolloverable”区域也仅限于链接中的文本，但不限于填充或其他任意尺寸。 因为这些链接中没有任何文本，所以可以，您将被限制在很小的区域内。

对我有用的是为链接提供背景图像-甚至是实际上不存在的背景图像。

因此，在仅IE的样式表中，尝试执行以下操作： 

#container_people a {
    background: url(trasparent.gif);  
 }

我发现图像文件（transparent.gif） 实际上并不存在 。 IE只是必须认为它存在。 是的，有点黑，但是可以用。

这为我解决了许多链接问题。

也许具有跨浏览器功能的javascript框架（例如jquery） （或一般而言）或jquery工具 （特殊覆盖...工具提示）值得一看。
