javascript - 菜单使用引导程序在移动版本中下推图像？

Question

这是导航栏的桌面版

这是单击汉堡按钮后屏幕尺寸变为移动版本时的图像

我希望当我单击汉堡包以打开菜单但如果它没有被按下，它将在图像上打开。

.navbar-light .navbar-toggler {
  outline: none !important;
  padding-top: 8px;
  padding-bottom: 2px;
  z-index: 1001;
}

.navbar-toggler .navbar-toggler-icon {
  background-color: black;
  color: black;
  height: 3px;
  display: block;
  margin-bottom: 6px;
}

<div class="container-fluid wow fadeIn">
  <nav class="navbar navbar-expand-md navbar-light bg-faded">
    <a class="navbar-brand wow fadeInLeft" href="#"><img src="img/logo.png" alt="logo" width="160px" height="60px"></a>
    <button aria-controls="navbarSupportedContent" aria-expanded="true" aria-label="Toggle navigation" class="navbar-toggler navbar-toggler-right" data-target="#navbarSupportedContent" data-toggle="collapse" type="button">
        <span class="navbar-toggler-icon"></span>
        <span class="navbar-toggler-icon"></span>
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav ml-auto wow fadeInRight">
        <li class="nav-item active">
          <a class="nav-link" href="#"><strong>HOME </strong><span class="sr-only">(current)</span></a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#"><strong>ABOUT</strong></a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#"><strong>SERVICES</strong></a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#"><strong>PORTFOLIO</strong></a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#"><strong>CONTACT US</strong></a>
        </li>
      </ul>
    </div>
  </nav>
</div>
<header id="home-section" class="mb-3">
  <img src="img/banner.jpg" alt="" width="100%">
</header>

我在哪里做错了？需要添加哪个 css 属性或引导类？

您可以使用.navbar-fixed-top课程将其固定在移动设备上
