按如下方式修改HTML：

<body>
  <nav class="navbar navbar-default" role="navigation">
    <div class="container-fluid">
      <div class="navbar-header">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbar-collapse-1">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>

我认为这应该适合你。

HTML：

<header>
    <div class="container">
        <div class ="row ">
            <div class="col-md-2">
                <a class ="navbar-brand" href=""><img src ="img/summan-company.png" alt="Summan" /></a>
                </div>
                <div class="col-md-10 pull-right row navbar-position">
                    <nav role="navigation" class="navbar navbar-default">
                        <div class="navbar-header">
                            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                               <span class="sr-only">Toggle navigation</span> 
                               <span class="icon-bar"></span> 
                               <span class="icon-bar"></span> 
                               <span class="icon-bar"></span> 
                            </button>
                        </div>

                        <div class="collapse navbar-collapse navbar-left ">
                            <ul class="nav navbar-nav ">
                                <li><a href="news.html">News</a></li>
                                <li><a href="products.html">Products</a></li>
                                <li><a href="contact.html">Contact</a></li>
                            </ul>
                        </div>
                    </nav>
                </div>
            </div>
        </div>
</header>
