Question

我正在使用bootstrap-3.3.7-dist。有人知道如何在向下滚动网页时将导航栏粘在上面吗？请帮忙。

这是HTML代码。

<div class="collapse navbar-collapse" id="myNavbar">
  <ul class="nav navbar-nav">
    <li><a href="index.html">Home Page</a></li>
    <li><a href="#business_register">Register</a></li>
    <li class="dropdown">

      <a class="dropdown-toggle" data-toggle="dropdown" href="#">Management <span class="caret"></span></a>
      <ul class="dropdown-menu">
        <li><a href="#upload_product">Upload</a></li>
        <li><a href="#sort_product">Sorting</a></li>
        <li><a href="#permission_management">Permission</a></li>
        <li><a href="#communicate">Communication</a></li>
        <li><a href="#basic_information">Information</a></li>
      </ul>
    </li>

  </ul>

</div>
