Question

我在Twitter Bootstrap的帮助下创建了一个简单的网页，最后的结果有几个问题：

虽然我已经为导航栏提供了一个＆＃34; navbar-inverse＆＃34;类，但它只显示为一个白色矩形，与网页内容的其余部分没什么区别。
我有三个带有空白href（href=""）的链接，但它们不会出现。

以下是我获得的结果的链接：http://jsbin.com/poqofapiqa/edit?html,output

Answer 1

导航栏：

使用navbar-dark和bg-dark类代替：
<nav class="navbar navbar-dark bg-dark"></nav>

链接：

至少使用<a href="#">...</a>，而不是空白href属性。具有空白属性的锚被解释为通常（非链接）元素

Answer 2

您正以错误的方式使用它。类nav-collapse用于显示移动菜单按钮。 nav-collapse中提供的内容不会显示在网页上。您可以将此代码用于您的菜单。

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/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>
    <ul class="nav navbar-nav">
      <li class="active"><a href="#">Home</a></li>
      <li><a href="#">Page 1</a></li>
      <li><a href="#">Page 2</a></li>
      <li><a href="#">Page 3</a></li>
    </ul>
  </div>
</nav>
  

</body>
</html>
