Question

我正在尝试更改悬停时导航栏链接的背景颜色和文本颜色但是我无法让它工作。无论我做什么，似乎都没有任何影响。

使用Pure CSS时我从未遇到过任何问题，但它主要是使用Bootstrap我遇到了这个问题

Answer 1

您的HTML代码显示navbar-static-top

<div class="navbar navbar-inverse navbar-static-top"></div>

在您的CSS中，您正在使用.navbar-fixed-top

.navbar .navbar-inverse .navbar-fixed-top > li > a:hover {
    color: cyan;
}

将您的代码更改为

.navbar.navbar-inverse.navbar-static-top li > a:hover {
    color: cyan;
}

Answer 2

根据您的代码，这是Sample jsFiddle。

只需将此css code添加到您的css：

即可

.navbar-inverse .navbar-nav > li > a {
  color: red;
}    
.navbar-inverse .navbar-nav > li > a:hover,
.navbar-inverse .navbar-nav > li > a:active,
.navbar-inverse .navbar-nav > li > a:focus{
  color: green;
  background-color: red;
}

只需将其更改为您想要的颜色。
