Question

菜单没有解开，当我点击我的按钮时我无法找出原因：

<nav class="navbar navbar-default">
<div class="container-fluid"> 

<div class="navbar-header"> <!-- start of colllapsed navbar-->
  <button
    type="button"
    class="navbar-toggle collapsed"
    data-target="#main_navbar"
    aria-expanded="false"
  >open!</button>
</div> <!-- end of colllapsed navbar-->

<div class="collapse navbar-collapse" id="main_navbar"> <!-- start of uncolllapsed navbar-->

        <ul class="nav navbar-nav">
          <li class="active"><a href="#">Home</a></li>
          <li><a href="#">My photos</a></li>
        </ul>
      </div> <!-- end of uncolllapsed navbar-->

    </nav>

    </div> <!-- end of container-->

是否与＆＃34; id＆＃34;？或者我在哪里弄错了？
