如何将导航栏与视频背景一起放置？

Question

我是 Bootstrap 的新手，我尝试实现一个带有视频背景的代码 navbar。

我尝试过的：

HTML代码：

<html>
  <head>
    <title>Medical</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">

    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css">
    <link href='https://fonts.googleapis.com/css?family=Montserrat:400,700' rel='stylesheet' type='text/css'>
    <link rel="stylesheet" href="CSS/wstyle.css">
  </head>
  <body>
    <section class="section-header">
      <div class="container">
        <div class="row">
          <div class="col-md-12">
            <nav class="navbar navbar-expand-lg navbar-light bg-light">
              <a class="navbar-brand" href="#">
                <img src="images/LOGO.png" style="width:60%" ;>
              </a>
              <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
              </button>
              <div class="collapse navbar-collapse" id="navbarTogglerDemo02">
                <ul class="navbar-nav ml-auto mt-2 mt-lg-0">
                  <li class="nav-item pl-4 pl-2 active">
                    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span>
                    </a>
                  </li>
                  <li class="nav-item pl-4 pl-2">
                    <a class="nav-link" href="#">About</a>
                  </li>
                </ul>
              </div>
            </nav>
          </div>
        </div>
      </div>
    </section>
    <section class="video-bg">
      <div class="container">
        <video id="video" autoplay loop>
          <source src="video/video.mp4" type="video/mp4">
        </video>
      </div>
    </section>
    <div id="location" class="container">
      <img src="images/image1.PNG" alt="IMAGE" width="100%" height="600px">
    </div>
  </body>
</html>

我已将 CSS 文件 (wstyle.css) 包含在文件夹 CSS 中，将视频 (video.mp4) 包含在视频文件夹中。

CSS 代码为：

CSS (wstyle.css)

.video-bg{
  position:fixed;
  z-index: -1;
}

现在，视频在 Internet Explorer 和 Google Chrome 中的播放方式不同，而且视频不作为导航栏的背景播放。如何让视频作为导航栏的背景播放？

类似这样。

    .navigation{

  padding-bottom:20px;
  position:absolute;
  top:0;
  width:100%;
  z-index:1;
  background-color: rgba(0,0,0,0.3); /** Change value according to you transperncy**/
}

.navbar-right{
  float:right;
  padding-right:10%;
}

.navbar-right a{
  text-decoration:none;
  padding:10px;
