Question

我已经找到了解决这个问题的答案，我想为HTML5背景视频添加控件，以便用户至少可以选择暂停视频以便于访问。内置的HTML5“控件”属性工作正常，但只要我添加CSS将视频放在后台，控件就会消失。如何保留控件并将视频置于后台？

这是我简单的HTML5代码：

<div class="fullscreen-bg">
    <video controls loop muted autoplay poster="Rustypic.jpg" class="fullscreen-bg-video">
        <source src="Rustybeg.webm" srclang="en" type="video/webm">
    </video>
</div>

这是我将视频放在后台的CSS：

.fullscreen-bg {
    position: fixed;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    overflow: hidden;
    z-index: -100;
}

.fullscreen-bg__video {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

Answer 1

this之类的内容怎么样？

.fullscreen-bg {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  overflow: hidden;
  z-index: -100;
}
.fullscreen-bg-video {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: -5;
}

<div class="fullscreen-bg">
  <video controls loop muted autoplay poster="Rustypic.jpg" class="fullscreen-bg-video">
    <source src="http://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">
  </video>
</div>
<div class="content">NASA is not about the ‘Adventure of Human Space Exploration’…We won’t be doing it just to get out there in space – we’ll be doing it because the things we learn out there will be making life better for a lot of people who won’t be able to go.</div>

Answer 2

只是一个注意事项 - 除非您因某种原因希望视频以页面为中心，否则您不需要100％的高度。
