- Go to the Vimeo video you want to embed.
- Click the "Share" button below the video.
- Click the "Embed" tab to get the embed code.
Example: Vimeo Embed Code
<iframe src="https://player.vimeo.com/video/VIDEO_ID" width="640" height="360" frameborder="0" allow="autoplay; fullscreen" allowfullscreen></iframe>Replace VIDEO_ID with the ID of the Vimeo video you want to embed.
You can customize the embedded Vimeo player by changing the URL parameters in the src attribute or by using the options in the embed code generator on Vimeo.
Embedding Audio from SoundCloud
SoundCloud provides an <iframe> embed code for embedding audio tracks into your web pages. To get the embed code for a SoundCloud track:
- Go to the SoundCloud track you want to embed.
- Click the "Share" button below the track waveform.

You can customize the embedded SoundCloud player by changing the URL parameters in the src attribute or by using the options in the embed code generator on SoundCloud.
Accessibility Considerations
When adding multimedia content to your web pages, you should think about accessibility for all users, including those with disabilities. Here are some key accessibility considerations to keep in mind:
Providing Alternative Content for Multimedia
To make your multimedia content accessible to users who may not be able to see or hear it, you should provide alternative content. This can include:
| Alternative Content | Description |
|---|---|
| Text transcripts | For audio content |
| Captions or subtitles | For video content |
| Descriptive text alternatives | For images and videos |
You can provide text transcripts and captions using the <track> element within the <audio> or <video> elements.
Example: Providing Alternative Content for Multimedia
<video src="video.mp4" controls>
<track src="captions.vtt" kind="captions" srclang="en" label="English Captions">
Your browser does not support the video element.
</video>The <track> element is used to specify a file (captions.vtt) that contains the captions for the video. The kind attribute is set to "captions" to indicate that the track is for captions, and the srclang attribute specifies the language of the captions.
Ensuring Keyboard Accessibility for Embedded Media
When embedding media from external sources like YouTube, Vimeo, or SoundCloud, you should make sure that the embedded media player is keyboard accessible. This means that users should be able to control the player using keyboard commands, such as:
- Spacebar to play/pause
- Arrow keys to seek forward or backward
- TAB key to move between controls
Most embedded media players from reputable sources are designed with keyboard accessibility in mind. However, you should test the keyboard accessibility of your embedded media to make sure it works as expected.
You should also provide clear instructions or labels for any custom media controls you create to make sure that all users, including those using assistive technologies, can understand and use them.
