这一直是我这一周的祸根。基本上我有一个纯 CSS 下拉菜单，它结合了标准列表和内容框作为子菜单。我在 IE 中遇到了麻烦，其中每个 LI 都有一个显示块标签，所以应该填充父 LI。所以我可以悬停并单击 LI 中的任何位置，链接悬停，活动状态处于打开状态。
如果我将鼠标悬停在文本上，则在 IE 中发生的情况是应用悬停状态样式没有问题，但是如果我将鼠标从文本上移开但仍在 LI 内，悬停会不断应用然后删除（请参阅dev.altech-英国网站）。
这有点烦人，因为子菜单一直在闪烁，而且您可能会错过子菜单。这些都不会发生在 FF、chrome、opera、safari 中。
下面是与此相关的 CSS 代码：
