Question

所以我有一个使用CSS / HTML / PHP构建的网站

标题包含我的导航栏。在过去的几个小时里，我一直在改变我的导航栏，看起来更好看。我得到了它我想要的方式它搞砸了我的侧栏后我不得不修复它和其他一些东西，现在它不再显示下拉菜单了。这是网站 Site link

有什么想法吗？

Answer 1

您将子菜单设置为display: none，但没有机制可以覆盖它。如果你添加这些样式，它应该工作：

#navbar li {position: relative;}

#navbar li ul {position: absolute; left: -9999px; display: block;}

#navbar li:hover ul {left: 0;}

下拉导航栏（CSS和HTML）无法正常工作
