下拉菜单(悬停)

时间:2017-01-30 12:55:06

标签: html css drop-down-menu hover

我不太确定我在这里做错了什么。当有人将鼠标悬停在导航项目上时(在这种情况下为" Products" Link),我想要一个标准的下拉导航块。我没有使用无序列表,只是链接。我设法将所有元素放在正确的位置,正确的格式看起来很棒。唯一的问题是,当我将鼠标悬停在主菜单按钮上时,我无法显示子菜单?无法弄清楚原因,对我来说看起来不错。我在谷歌浏览器中进行预览

CSS代码中的最后几个似乎是错误的,但我无法弄清楚到底是什么。我已经观看了很多关于这个的视频,并且已经格式化了css代码,以几种不同的方式显示子菜单,但我无法弄明白。

您应该考虑使用无序列表,以便更容易地显示子菜单。

在没有其他菜单项的情况下,我快速解决了您的问题。

我将你的html和css更改为以下内容:

是的,谢谢,我已经做到了,现在看起来好多了。我现在的问题是当子菜单弹出时,下一个主菜单项被推到子菜单的底部。当我尝试将鼠标悬停在子菜单上时,只要我的鼠标从主导航项目中移除,它就会立即消失。

如果要在下拉菜单中使用CSS悬停样式,则它必须是悬停元素的子项。 否则,您可以在此下拉菜单中使用jQuery / javascript。 我有另一个想法来解决这个问题。请检查此链接:
