引导移动菜单按钮不可见

Bootstrap mobile menu button not visible

当引导菜单显示在移动视图中时，我无法查看它的菜单按钮。同时，我需要删除 Bootstrap 提供的所有 UI 样式，并拥有自己的导航栏样式。

<nav class="navbar-fixed-top" role="navigation">
  <div class="container-fluid">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">WebSiteName</a>
    </div>
    <div class="collapse navbar-collapse" id="myNavbar">
      <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>
      <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>

您应该添加导航栏默认或导航栏导航栏反向，以便导航链接、按钮等应用颜色/状态。

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">

如果你想要一个透明或白色的背景USS CSS。
