css - Bootstrap 布局导航栏和菜单

Question

我正在使用 Bootstrap v3 进行布局，并在导航栏中添加了一个下拉菜单，但是当我添加 btn-primary 时，文本是黑色的，所以看不到，如果我删除 btn-primary，那么 Angular 半径似乎与菜单。

感谢任何帮助。

<div class="container">
  <div class="col-md-12 column">
    <nav class="navbar navbar-default" role="navigation">
      <div class="navbar-header">
        <a class="navbar-brand" href="Javascript:void(0);">Title Information </a>
      </div>

      <ul class="nav navbar-nav navbar-right">

        <li class="dropdown btn-primary">
          <a class="dropdown-toggle btn-primary" href="Javascript:void(0);" data-toggle="dropdown">Actions<strong class="caret"></strong></a>
          <ul class="dropdown-menu">
            <li>
              <a href="#">Action 1</a>
            </li>
            <li>
              <a href="#">Action 2</a>
            </li>
            <li>
              <a href="#">Action 3</a>
            </li>
            <li class="divider"></li>
            <li>
              <a href="#">Close</a>
            </li>
          </ul>
        </li>
      </ul>
  </div>

  </nav>
  <div role="tabpanel" class="col-md-12 column">

    <!-- Nav tabs -->
    <ul class="nav nav-tabs" role="tablist">
      <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
      <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
      <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
      <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
    </ul>

    <!-- Tab panes -->
    <div class="tab-content">
      <div role="tabpanel" class="tab-pane active" id="home">...</div>
      <div role="tabpanel" class="tab-pane" id="profile">...</div>
      <div role="tabpanel" class="tab-pane" id="messages">...</div>
      <div role="tabpanel" class="tab-pane" id="settings">...</div>
    </div>

  </div>

Answer 1

取出“btn-primary”，但仅将其更改为“btn”，这样应该可以解决问题。
