Introduction

In the previous topic, we explored how to insert images into web pages using the <img> tag. In this topic, we'll delve into the world of multimedia and learn how to embed videos and audio files into web pages using the <video> and <audio> tags. These tags allow us to add rich media content to our websites, enhancing user engagement and experience.

The <video> tag

The <video> tag is used to embed video content into a web page. The basic syntax of the <video> tag is as follows:

<video src="video.mp4" width="640" height="480" controls></video>

Here, src specifies the source of the video file, width and height define the dimensions of the video player, and controls attribute adds video controls such as play, pause, and volume.

Attributes of the <video> tag

The following are some commonly used attributes of the <video> tag:

• src: Specifies the source of the video file.
• width and height: Define the dimensions of the video player.
• controls: Adds video controls such as play, pause, and volume.
• autoplay: Specifies whether the video should start playing automatically.
• loop: Specifies whether the video should loop continuously.
• muted: Specifies whether the video should be muted by default.

Example

<video src="video.mp4" width="640" height="480" controls autoplay loop muted></video>

This code will embed a video that starts playing automatically, loops continuously, and is muted by default.

The <audio> tag

The <audio> tag is used to embed audio content into a web page. The basic syntax of the <audio> tag is as follows:

<audio src="audio.mp3" controls></audio>

Here, src specifies the source of the audio file, and controls attribute adds audio controls such as play, pause, and volume.

Attributes of the <audio> tag

The following are some commonly used attributes of the <audio> tag:

• src: Specifies the source of the audio file.
• controls: Adds audio controls such as play, pause, and volume.
• autoplay: Specifies whether the audio should start playing automatically.
• loop: Specifies whether the audio should loop continuously.
• muted: Specifies whether the audio should be muted by default.

Example

<audio src="audio.mp3" controls autoplay loop muted></audio>

This code will embed an audio file that starts playing automatically, loops continuously, and is muted by default.

Supported Video and Audio Formats

Different browsers support different video and audio formats. Here are some of the most commonly supported formats:

• Video formats: MP4, WebM, OGV
• Audio formats: MP3, WAV, OGG

Tips and Best Practices

• Always provide a fallback for older browsers by using the <source> tag to specify multiple file formats.
• Use the preload attribute to specify how much of the video/audio file should be preloaded.
• Use the poster attribute to specify a poster image for the video player.
• Consider using a video/audio player library such as Plyr or Video.js for more advanced features and customization options.
