javascript - 重新定位 HTML5 视频搜索栏

Question

我正在尝试用 HTML 创建一个模拟页面，在后台全屏播放视频。我有一个透明的图像，覆盖了模拟播放按钮和标题的背景视频(所有按钮只是一个图像，而不是真实的!)。

现在我需要在视频标签中插入一个真实搜索栏和 slider ，其宽度和位置可调节，如下所示。我怎样才能做到这一点？

这是到目前为止我的简单代码。静态图片为HERE视频是HERE .

video#backgroundvid {
  position: fixed;
  right: 0;
  bottom: 0;
  min-width: 100%;
  min-height: 100%;
  width: auto;
  height: auto;
  z-index: -100;
  background-repeat: no-repeat;
}

<img src="/image/gmK7P.png" style="object-fit:cover" alt="">
<video preload="auto" autoplay loop id="backgroundvid">
  <source src="https://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">
  Your browser does not support HTML5 video.
</video>

你结账了吗？ MDN: Video player styling basics ？

编辑:以下是带有叠加层的进度条示例。您可能需要搞乱元素定位，但您应该正确地嵌套/范围化您的元素。

const player = document.querySelector('.video-player');
const video = player.querySelector('video');
const progressBar = player.querySelector('.progress-bar');

video.addEventListener('timeupdate', updateProgressBar, false);
progressBar.addEventListener('click', seek);

function updateProgressBar() {
  var percentage = Math.floor((100 / video.duration) * video.currentTime);
  progressBar.value = percentage;
  progressBar.innerHTML = percentage + '% played';
}

function seek(e) {
  let percent = e.offsetX / this.offsetWidth;
  video.currentTime = percent * video.duration;
  e.target.value = Math.floor(percent / 100);
  e.target.innerHTML = progressBar.value + '% played';
}

.video-player {
  position: relative;
  width: 66%;
  height: 66%;
}
.video-player img {
  width: 100%;
  height: 100%;
}
.video-player video {
  position: fixed;
  top: 0;
  left: 0;
  min-width: 66%;
  min-height: 66%;
  width: auto;
  height: auto;
  z-index: -100;
  background-repeat: no-repeat;
}
.video-player .controls {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
}
.video-player .controls .progress-bar {
  position: absolute;
  margin-left: 28%;
  bottom: 10%;
  color: orange;
  font-size: 12px;
  width: 40%;
  height: 8%;
  border: none;
  background: #434343;
  border-radius: 9px;
  vertical-align: middle;
  cursor: pointer;
}
.video-player .controls progress::-moz-progress-bar {
  color: orange;
  background: #434343;
}
.video-player .controls progress[value]::-webkit-progress-bar {
  background-color: #434343;
  border-radius: 2px;
  box-shadow: 0 2px 5px rgba(0, 0, 0, 0.25) inset;
}
.video-player .controls progress[value]::-webkit-progress-value {
  background-color: orange;
}

<div class="video-player">
  <video preload="auto" autoplay loop id="backgroundvid">

这是一个带有自定义控件的示例。这是 Rob Gravelle 的镜子 HTML5 Video Player with Custom Controls 。大多数样式都在那里定义。

注意进度条样式。

progress::-moz-progress-bar {

progress[value]::-webkit-progress-bar {
  background-color: #434343;
  border-radius: 2px;
  box-shadow: 0 2px 5px rgba(0, 0, 0, 0.25) inset;
}
