问题描述
我想放置一个html5视频(当然有视频标签),宽度为100%,高度为100%,将在后台播放。这里是一个图像的例子,我想要一个视频,我只是没有找到如何做到:
I want to place a html5 video (with the video tag of course) with 100% width and 100% height which will play in the background. Here is an example with an image and I want exactly the same with a video, I just didn't find out how to do that:
#image {
background-image: url("image.jpg");
background-repeat: no-repeat;
background-size: 100% 100%;
width: 100%;
height: 100%;
position: fixed;
top: 0;
left: 0;
}

推荐答案
您可以尝试:
header {
position: relative;
background-size: cover;
background-position: 50% 50%;
height: 100vh;
z-index: 0;
}
header h1 {
text-align: center;
font: 3em/1.4 helvetica neue, helvetica, arial, sans-serif;
color: #fff
}
header video {
-webkit-transform: translateX(-50%) translateY(-50%);
-moz-transform: translateX(-50%) translateY(-50%);
-ms-transform: translateX(-50%) translateY(-50%);
-o-transform: translateX(-50%) translateY(-50%);
transform: translateX(-50%) translateY(-50%);
position: absolute;
top: 50%;
left: 50%;
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
z-index: -100;
}
<header>
<h1>Sample Title</h1>
<video autoplay loop class="bg-video">
<source src="https://d2v9y0dukr6mq2.cloudfront.net/video/preview/abstract-rainbow_wjpctkdes__PM.mp4" type="video/mp4">
</video>
</header>
strong>保持高宽比和视频居中,同时始终完全覆盖容器。
It will keep the aspect ratio and the video centered while always fully covering the container.
