Question

我有以下代码：

＆＃13;

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Case</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
  <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
</head>
<body>

<nav class="navbar navbar-inverse">
  <div class="container-fluid">
    <div class="navbar-header">
      <a class="navbar-brand" href="#">WebSiteName</a>
    </div>
    <div>
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Home</a></li>
        <li class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Page 1 <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Page 1-1</a></li>
            <li><a href="#">Page 1-2</a></li>
            <li><a href="#">Page 1-3</a></li>
          </ul>
        </li>
        <li><a href="#">Page 2</a></li>
        <li><a href="#">Page 3</a></li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <li><a href="#"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li>
        <li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a></li>
      </ul>
    </div>
  </div>
</nav>
  
<div class="container">
  <h3>Right Aligned Navbar</h3>
  <p>The .navbar-right class is used to right-align navigation bar buttons.</p>
</div>

</body>
</html>

＆＃13;

如果您运行代码，您可以注意到所有按钮（例如WebsiteName，Page1,2,3，注册和登录）都是灰色的。除了HOME。如何停用灰色按钮？

Answer 1

见下文。

但这不是最好的情况。最好在CSS中进行全局更改。

Answer 2

您需要将默认灰色覆盖为白色。您所指的active状态与此无关，因为它是功能而非演示。需要对CSS进行更改。

＆＃13;

.navbar.navbar-inverse .navbar-brand {
  color: #fff;
}
.navbar.navbar-inverse .navbar-nav > li > a {
  color: #fff;
}
