Question

任何人都知道为什么我的网页加载与导航栏预先查看此代码切换下来？

导航栏加载扩展，但随后单击切换按钮将其刷新到扩展位置。第二次单击，然后缩回导航栏，以我想它在初始位置

<div class="nav-gradient"> 
    <nav class="navbar navbar-default navbar-fixed-top"> 
     <div> 
      <!-- Brand and toggle get grouped for better mobile display --> 
      <div class="navbar-header"> 
       <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> 
        <span class="sr-only">Toggle navigation</span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span> 
       </button> 
      </div> 

      <!-- Collect the nav links, forms, and other content for toggling -->
