Audio and video 1

In this task, we want you to embed an audio file onto the page.

To complete this task:

Add the path to the audio file to an appropriate attribute to embed it on the page. The audio is called audio.mp3, and it available at a path of https://github.com/mdn/learning-area/raw/refs/heads/main/html/multimedia-and-embedding/tasks/media-embed/media/audio.mp3.
Add an attribute to make browsers display some default controls.

The starting point of the task looks like this:

Here's the underlying code for this starting point:

html

<h1>Basic audio embed</h1>

<audio></audio>

body {
  background-color: white;
  color: #333333;
  font:
    1em / 1.4 "Helvetica Neue",
    "Helvetica",
    "Arial",
    sans-serif;
  padding: 1em;
  margin: 0;
}

* {
  box-sizing: border-box;
}

audio,
video {
  border: 1px solid black;
}

<audio
  controls
  src="https://github.com/mdn/learning-area/raw/refs/heads/main/html/multimedia-and-embedding/tasks/media-embed/media/audio.mp3"></audio>

Audio and video 2

In this task, we want you to mark up a slightly more complex video player, with multiple sources, subtitles, and other features besides.

To complete this task:

Add an attribute to make browsers display some default controls.
Add multiple sources, containing the paths to the video files. The files are called video.mp4 and video.webm, and are available at the following paths:
1. https://github.com/mdn/learning-area/raw/refs/heads/main/html/multimedia-and-embedding/tasks/media-embed/media/video.mp4
2. https://github.com/mdn/learning-area/raw/refs/heads/main/html/multimedia-and-embedding/tasks/media-embed/media/video.webm
Let the browser know in advance what video formats the sources point to, so it can make an informed choice of which one to download ahead of time.
Give the <video> a width and height equal to its intrinsic size (320 by 240 pixels).
Make the video muted by default.
Display the text tracks contained in the media folder, in a file called https://raw.githubusercontent.com/mdn/learning-area/refs/heads/main/html/multimedia-and-embedding/tasks/media-embed/media/subtitles_en.vtt, when the video is playing. You must explicitly set the type as subtitles, and the subtitle language to English.
Make sure the readers can identify the subtitle language when they use the default controls.
