Div元素在移动设备中查看时移动

Question

我在移动设备上查看网站时遇到问题，屏幕上的飞出菜单图标和主图标丢失了。这可能是由于引导代码的输入不正确，但它很难修复。

Bootstrap code for icons

        <div class="container-fluid">


            <!-- change the image in style.css to the class header .container-fluid [approximately row 50] -->
            <div class="container">
   <header id="home">
            <!-- change the image in style.css to the class header .container-fluid [approximately row 50] -->
            <div class="container">
              <div class="row">
                    <div class="col-md-12 col-xs-12"></div>
                <div class="col-md-1 col-md-offset-10 col-xs-2 text-center">
                    <a href="#" class="thumbnail logo"><img src="images/MJW Star3.png" alt="" class="img5"></a></span>
                    <div class="col-md-10 col-md-offset-8 col-xs-2 text-center">
                        <div class="menu-btn"><span class="hamburger">&#9776;</span>
