How to use HTML, CSS and jQuery to make a responsive video player

With the rapid development of the Internet, video players have become essential on the Internet a tool. How to make a responsive video player? This article will introduce how to use HTML, CSS and jQuery to implement a simple responsive video player, and provide specific code examples.

1. Create HTML structure

First, we need to create a basic HTML structure to place the various elements of the video player. The following is a simple HTML structure example:

<div class="video-player">
  <video id="my-video" controls>
    <source src="video.mp4" type="video/mp4">
    Your browser does not support the video tag.
  </video>
  <div class="controls">
    <button class="play-pause"></button>
    <div class="progress-bar">
      <div class="progress"></div>
    </div>
    <div class="volume-bar">
      <div class="volume"></div>
    </div>
  </div>
</div>

In the above HTML code, we have created a <div> element with the "video-player" class, containing A <code><video></video> element is used to play videos, as well as some control buttons and progress bars, etc.

2. Write CSS styles

Next, we need to write CSS styles to beautify the video player. The following is a simple CSS style example:

.video-player {
  position: relative;
  width: 100%;
  max-width: 800px;
  margin: 0 auto;
}

.video-player video {
  width: 100%;
  height: auto;
}

.controls {
  position: absolute;
  bottom: 0;
  left: 0;
  right: 0;
  background-color: rgba(0, 0, 0, 0.4);
  display: flex;
  justify-content: space-between;
  padding: 5px;
}

.play-pause {
  background-image: url(play-pause.png);
  background-size: cover;
  width: 30px;
  height: 30px;
  cursor: pointer;
}

.progress-bar {
  flex-grow: 1;
  height: 5px;
  background-color: #fff;
  margin: 10px;
}

.progress {
  height: 100%;
  background-color: #ff0000;
  width: 0;
}

.volume-bar {
  flex-grow: 1;
  height: 5px;
  background-color: #fff;
  margin: 10px;
}

.volume {
  height: 100%;
  background-color: #ff0000;
  width: 50%;
}

In the above CSS code, we set the size, position, color and other styles of the video player, as well as the styles of control buttons and progress bars, etc.

3. Use jQuery to add interactive features

Finally, we use jQuery to add interactive features so that the video player can respond to user operations. The following is a simple jQuery code example:

$(document).ready(function() {
  var video = $("#my-video")[0];
  var playPauseBtn = $(".play-pause");
  var progressBar = $(".progress");
  var volumeBar = $(".volume");

  playPauseBtn.on("click", function() {
    if (video.paused) {
      video.play();
      playPauseBtn.css("background-image", "url(pause.png)");
    } else {
      video.pause();
      playPauseBtn.css("background-image", "url(play.png)");
    }
  });

  video.addEventListener("timeupdate", function() {
    var progress = video.currentTime / video.duration * 100;
    progressBar.width(progress + "%");
  });

  volumeBar.on("click", function(event) {
    var volume = event.offsetX / volumeBar.width();
    video.volume = volume;
    volumeBar.width(volume * 100 + "%");
  });
});

In the above jQuery code, we use the document.ready() method to ensure that the page is loaded before executing the code. Then, we obtain elements such as video elements, play buttons, progress bars, and volume bars, and add corresponding event handlers to control playback, progress, volume, etc.

At this point, a simple responsive video player is completed. You can further beautify and expand it according to your needs.
