如何创建具有一定边距的全屏背景视频？

Question

目标网页上有一个全屏背景视频，涵盖了整个视口。我想实际包含视频，并在所有屏幕尺寸的左侧和右侧显示一些白色。我尝试将容器的宽度和高度更改为没有运气...我还添加了一些边距，但是随着屏幕变小，它们会消失。有什么想法吗？

    .vid {
      position: relative;
      height: 100vh;

 
    }

    .video-container:before {
      content:"";
      position: absolute;
      top:0;
      right:0;
      left:0;
      bottom:0;
      z-index:1;
      background: rgba(0,0,0,.75);
      opacity: .5;
      }


    .video-container {
      position: absolute;
      top: 0;
      left: 0;
      height: 100%;
      width: 100%;
      z-index: -1;
 
    }

    .bg-video {
     height: 100%;
     width: 100%;
     object-fit: cover;

     }

    <section class="vid p-5">
        <div class="video-container h-100">
            <video class="bg-video" autoplay muted loop>

Answer 1

您需要将width设置为父母div，并将margin:0 auto赋予该div。

尝试一下：

.vid {
    position: relative;
    height: 100vh;
    width: 80%;
    margin: 0 auto;
}
