Embedding audio and video elements in web pages enhances the multimedia experience for users. HTML5 introduced the <audio> and <video> tags, which provide a standardized way to embed media without relying on external plugins like Flash. This article explores how to use these elements, along with examples and visible outputs.
The <audio> Element
The <audio> element is used to embed sound content in web pages. It supports various attributes to control playback and provide a better user experience.
Basic Usage
Here’s how to embed a simple audio file:
html<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Audio Element Example</title>
</head>
<body>
<h2>Audio Example</h2>
<audio controls>
<source src="example.mp3" type="audio/mpeg">
<source src="example.ogg" type="audio/ogg">
Your browser does not support the audio element.
</audio>
</body>
</html>
The <video> Element
The <video> element embeds video content. It supports attributes similar to those of the <audio> element to control playback, as well as additional attributes for video-specific controls.
Basic Usage
Here’s how to embed a simple video file:
html<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Video Element Example</title>
</head>
<body>
<h2>Video Example</h2>
<video width="320" height="240" controls>
<source src="example.mp4" type="video/mp4">
<source src="example.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
</body>
</html>
Attributes for <audio> and <video> Elements
Both <audio> and <video> elements share several attributes:
- controls: Displays built-in playback controls (play, pause, volume).
- autoplay: Starts playing the media as soon as it is ready.
- loop: Repeats the media after it ends.
- muted: Mutes the media.
- preload: Specifies how the media should be loaded when the page loads. Values include
auto,metadata, andnone.

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

</video>
</body>
</html>
Providing Multiple Sources
To ensure compatibility with different browsers, it’s a good practice to provide multiple sources for your audio and video files. This allows the browser to choose the format it supports.
Example with Multiple Sources
html<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Media with Multiple Sources</title>
</head>
<body>
<h2>Audio with Multiple Sources</h2>
<audio controls>
<source src="example.mp3" type="audio/mpeg">
<source src="example.ogg" type="audio/ogg">
Your browser does not support the audio element.
</audio>
<h2>Video with Multiple Sources</h2>
<video width="320" height="240" controls>
<source src="example.mp4" type="video/mp4">
<source src="example.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
</body>
</html>
Accessibility Considerations
To make audio and video content accessible:
- Captions and Subtitles: Provide captions for the hearing impaired. Use the
<track>element within the<video>tag for captions. - Transcripts: Offer a text version of the media content for users who cannot access audio or video.
Example with Captions
html<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Accessible Video Example</title>
</head>
<body>
<h2>Video with Captions</h2>
<video width="320" height="240" controls>
<source src="example.mp4" type="video/mp4">
<track src="captions.vtt" kind="captions" srclang="en" label="English">
Your browser does not support the video tag.
</video>
</body>
</html>
