The <track> element is supported in all modern browsers (from IE10+ for full functionality).
Older browsers may ignore subtitle tracks or not display them in the video controls.
To switch between the subtitles click on three vertical dots at bottom right of the video and then click on CC (captions) and choose the desired subtitle.
Notes
- The text file used in
srcmust be in WebVTT (.vtt) format. - The
kindattribute determines the purpose of the track (e.g., subtitles for translation, captions for hearing-impaired users). - You can include multiple
<track>tags for different languages or purposes. - The
<track>element is empty, meaning it doesn’t have a closing tag.
Conclusion
The <track> tag enhances accessibility and internationalization in multimedia content.
By including properly formatted caption or subtitle files, you make your videos more inclusive and user-friendly for a global audience.
