# Closed captions and subtitles
Compare sideloaded subtitles with captions and subtitles included in a stream. For sideloaded text tracks, set `format` on the text track description (for example, `'srt'`, `'webvtt'`, and other supported formats).
Tip: open your browser's developer console and use the `player` and `THEOplayer` variables to interact with this demo.

WebVTT, TTML, and CEA-608 tracks can be included in a manifest. You can also add a subtitle file when setting the source. The demo filters out metadata tracks and reports each text track's label, language, kind, format, and mode.
## Style subtitles
You can set `player.textTrackStyle` directly. See the [`TextTrackStyle` API](https://optiview.dolby.com/docs/theoplayer/v11/api-reference/web/interfaces/TextTrackStyle) for supported properties.
```js
player.textTrackStyle = {
backgroundColor: 'rgba(0, 0, 0, 0.85)',
edgeStyle: 'dropshadow',
fontColor: '#ffff00',
fontSize: '150%',
};
```
See [how to insert subtitles](https://optiview.dolby.com/docs/theoplayer/how-to-guides/web/text-tracks/insert-subtitles.md) for more details.
