如何在 bootstrap 导航栏中制作彩色按钮？

Question

我想在导航栏中有一个带有白色文本的大红色 "Donate" 按钮，我的解决方案是 <a href="#" class="btn btn-danger">Donate Now</a>。但是，该按钮似乎在悬停时变为透明。

我也试过<span class="label label-danger">Danger</span>和<p class="btn btn-danger">Donate Now</p>，但是前者太小了，而后者悬停起来很奇怪

<head>

  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <!-- Bootstrap -->
  <link href="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
  <link href="/static/knowledge/index.css" rel="stylesheet">
</head>

<body>
  <div class="header">
    <nav class="navbar navbar-default navbar-static-top">
      <div class="container-fluid">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
        </div>
        <div id="navbar" class="navbar-collapse collapse">
          <ul class="nav navbar-nav navbar-right">
            <li>
              <a href="#" class="btn btn-danger">Donate Now</a>
            </li>
          </ul>
        </div>
        <!--/.nav-collapse -->
      </div>
    </nav>
  </div>
</body>

为了防止上面的代码无法重现我的问题，我还创建了这个fiddle。

Answer 1

在您的自定义样式上尝试此代码sheet

.navbar-default .navbar-nav>li>a:focus, .navbar-default .navbar-nav>li>a:hover {
    color: #333;
    background-color: red!important;
    border: 1px solid red!important;
}

    </div>
  </div>
</nav>
  
<div class="container">
  <h3>Collapsible Navbar</h3>
  <p>In this example, the navigation bar is hidden on small screens and replaced by a button in the top right corner (try to re-size this window).
  <p>Only when the button is clicked, the navigation bar will be displayed.</p>
</div>

Answer 3

您在 fiddle 中使用了标签而不是按钮。并且您不应该在导航 link 所属的位置使用按钮，但您可以使用简单的包装器绕过它。

<li>
    <span>
       <a class="btn btn-danger btn-lg">Donate Now</a>
    </span>
</li>
