所以我有一个使用 CSS / HTML / PHP 构建的网站

标题包括我的导航栏。在过去的几个小时里，我一直在改变我的导航栏，让它看起来更好。在它搞砸了我的侧栏之后，我得到了它想要的方式，我不得不修复它和其他一些东西，现在它不会再显示下拉菜单了。这是网站 网站链接

这是我正在使用的代码

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

#navbar li {position: relative;}

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

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