如何创建全屏视频

步骤1)添加HTML:

示例

<!-- The video -->
<video autoplay muted loop id="myVideo">
  <source src="rain.mp4" type="video/mp4">
</video>

<!-- Optional: some overlay text to describe the video -->
<div class="content">
  <h1>Heading</h1>
  <p>Lorem ipsum...</p>
  <!-- Use a button to pause/play the video with JavaScript -->
  <button id="myBtn" onclick="myFunction()">Pause</button>
</div>

步骤2)添加CSS:

示例

/* Style the video: 100% width and height to cover the entire window */
#myVideo {
  position: fixed;
  right: 0;
  bottom: 0;
  min-width: 100%;
  min-height: 100%;
}

/* Add some content at the bottom of the video/page */
.content {
  position: fixed;
  bottom: 0;
  background: rgba(0, 0, 0, 0.5);
  color: #f1f1f1;
  width: 100%;
  padding: 20px;
}

/* Style the button used to pause/play the video */
#myBtn {
  width: 200px;
  font-size: 18px;
  padding: 10px;
  border: none;
  background: #000;
  color: #fff;
  cursor: pointer;
}

#myBtn:hover {
  background: #ddd;
  color: black;
}


步骤 3) 添加 JavaScript:

或者,您可以添加 JavaScript,只需单击按钮即可暂停/播放视频:

示例

<script>
// Get the video
var video = document.getElementById("myVideo");

// Get the button
var btn = document.getElementById("myBtn");

// Pause and play the video, and change the button text
function myFunction() {
  if (video.paused) {
    video.play();
    btn.innerHTML = "Pause";
  } else {
    video.pause();
    btn.innerHTML = "Play";
  }
}
</script>
