Answer 1

问题是你错过了添加navbar-header容器，这有助于隔离标题和子菜单。希望它有所帮助

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<nav class="navbar navbar-default navbar-fixed-top">
  <div class="container">
    <div class="navbar-header">
      <a class="navbar-brand" href="#page-top">Title</a>
      <button class="navbar-toggle" data-toggle="collapse" data-target="#dropdown">
                Menu
            </button></div>
    <div class="collapse navbar-collapse" id="dropdown">
      <ul class="nav navbar-nav navbar-right">
        <li>
          <a href="#">Link 1</a>
        </li>
        <li>
          <a href="#">Link 2</a>
        </li>
        <li>
          <a href="#">Link 3</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

Answer 2

在div id =“dropdown”中添加类.m-top-55，它适用于小布局

@media only screen and (min-width: 600px) {
    /* For tablets: */
    .m-top-55{
       margin-top:55px;
     }
}

这将解决您的问题。
