Question

我无法摆脱视频中的iframe边框。每当我将我的视频分配为iframe时，它都会在视频的两侧创建黑色边框。我希望我的视频全屏显示，没有黑色边框。我试过frameborder =“ 0”，border =“ 0”，依此类推。而且没有任何效果。但是，如果可以在Google Chrome浏览器中自动播放视频，则无需使用iframe。我知道Chrome不允许在不静音的情况下自动播放视频，但是当有人降落在页面上时，我确实需要声音。否则，我将无法获得想要的影响。有没有办法通过代码或其他视频代码类型来覆盖此问题？请让我知道是否可以帮忙。

这是HTML：

这是CSS：

body{
    margin: 20px;
}


iframe{
    position: fixed;
    right: 0;
    bottom: 0;
    min-width: 100%;
    min-height: 100%;
    z-index: -1;
}

h4{
    
    color: white;
    text-align: center;
    opacity: 0.8;
}

header{
    z-index:2;
    text-align: center;
    color: white;
    font-size: 70px;
    opacity: 0.9;
}

span{
    
        color: white;
        padding: 20px;
    padding-left: 110px;
        z-index: 1;
        border-top: 70px;
    }

.overlay {
  height: 100%;
  width: 0;
  position: absolute;
  z-index: 1;
  top: 0;
  left: 0;
  background-color: rgb(0,0,0);
  background-color: rgba(0,0,0, 0.9);
  overflow-x: hidden;
  transition: 0.5s;
}

.overlay-content {
  position: relative;
  top: 25%;
  width: 100%;
  text-align: center;
  margin-top: 30px;
}

.overlay a {
  padding: 8px;
  text-decoration: none;
  font-size: 36px;
  color: #818181;
  display: block;
  transition: 0.3s;
}

.overlay a:hover, .overlay a:focus {
  color: #f1f1f1;
}

.overlay .closebtn {
  position: absolute;
  top: 20px;
  right: 45px;
  font-size: 60px;
}

@media screen and (max-height: 450px) {
  .overlay a {font-size: 20px}
  .overlay .closebtn {
  font-size: 40px;
  top: 15px;
  right: 35px;
