如何在引导程序导航栏上添加背景悬停颜色？

Question

我试图在将鼠标悬停在链接上时为其添加背景颜色，并在将它们悬停时更改社交媒体图标的颜色。

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选择器来更改:hover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得上述代码的实际示例：

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

 <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.0/umd/popper.min.js"></script><script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script><link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet"/> <nav class="navbar navbar-expand-lg navbar-light bg-light"> <a class="navbar-brand" href="#"> <img src="//picsum.photos/50/50" class="img-responsive logo"></a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarText"> <ul class="navbar-nav mr-auto"> <li class="nav-item"> <a class="nav-link" href="#">Featured</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Brand new</a> </li> </ul> <a class="navbar-text" href="#"> <img src="insta.png" width="30"height="30" alt=""> </a> <a class="navbar-text" href="#"> <img src="Twitter.png" width="30"height="30" alt=""> </a> <a class="navbar-text" href="#"> <img src="facebook.png" width="30"height="30" alt=""> </a> </div> </nav>
