如何在网站 HTML/CSS 上放置背景视频循环

How to put a background video loop on a website HTML/CSS

提问by duhzecca

I'm trying to put a video as a background video on my website. I've researched a lot and it is not working and I don't know why.

我正在尝试将视频作为背景视频放在我的网站上。我已经研究了很多，但它不起作用，我不知道为什么。

On my html I have:

在我的 html 上，我有：

<video id="bgVideo" controls preload="true" autoplay loop muted>
    <source src="../images/Home_Page.mp4" type="video/mp4" >
    <source src="../images/Home_Page.ogv" type="video/ogg" >    
    <source src="../images/Home_Page.webm" type="video/webm" > 
</video>     
<script src="scripts/html5ext.js" type="text/javascript"></script> 

And on my CSS I have:

在我的 CSS 上，我有：

body
{
background:  url("../images/Home_Page.png") no-repeat fixed center;
}

video#bgVideo {
position: fixed;
right: 0;
bottom: 0;
width: auto;
min-width: 100%;
height: auto;
min-height: 100%;
z-index: -100;    
background-size: cover;
}

However, the video is not playing and the background stays white. Any suggestions to solve this problem??

但是，视频没有播放，背景保持白色。有什么建议可以解决这个问题吗？？

Thank you so much

非常感谢

this should work

这应该有效

   <video id="bgVideo" controls preload="true" autoplay loop muted>
      <source src="Home_Page.mp4" type="video/mp4" > 
       <source src="Home_Page.ogv" type="video/ogv" >    
      <source src="Home_Page.webm" type="video/webm" > 

   </video>

Also you should create a htaccess file/amend your htaccess file to include the following

您还应该创建一个 htaccess 文件/修改您的 htaccess 文件以包括以下内容

   AddType video/mp4 .mp4 .m4v
   AddType video/ogg .ogv
   AddType video/webm .webm

This code is worked for me its providing full screen video.

这段代码对我有用，它提供全屏视频。

var vid = document.getElementById("bgvid");
var pauseButton = document.querySelector("#polina button");

if (window.matchMedia('(prefers-reduced-motion)').matches) {
    vid.removeAttribute("autoplay");
    vid.pause();
    pauseButton.innerHTML = "Paused";
}

function vidFade() {
  vid.classList.add("stopfade");
}

vid.addEventListener('ended', function()
{
// only functional if "loop" is removed 
vid.pause();
// to capture IE10
vidFade();
}); 


pauseButton.addEventListener("click", function() {
  vid.classList.toggle("stopfade");
  if (vid.paused) {
    vid.play();
    pauseButton.innerHTML = "Pause";
  } else {
    vid.pause();
    pauseButton.innerHTML = "Paused";
  }
})

body {
  margin: 0;
  background: #000; 
}
video { 
    position: fixed;
    top: 50%;
    left: 50%;
