如何在引导导航栏上添加背景悬停颜色

Question

当我将鼠标悬停在链接上时，我正在尝试为链接添加背景颜色并在我也将鼠标悬停在社交媒体图标上时更改它们的颜色。

我已经查看并尝试了很多我搜索过的答案，但是当我尝试时它仍然对我不起作用。

有人可以帮忙吗？非常感谢

Answer 1

只需使用 :hover 选择器更改悬停的菜单项的 background-color 属性，如下所示：

.nav-item:hover {
  background-color: red;
}
.navbar-text:hover {
  background-color: red;
}

检查并运行以下代码片段以获取上述代码的实际示例：

.nav-item:hover {
  background-color: red;
}
