How it works?

Coursera is using WebVTT (Web Video Text Tracks) for showing subtitles inside the video element.

WebVTT allows us to read the subtitles text and the other properties by the TextTrack interface.

When the value of the Mode property is 'showing', we can see that this text is displayed in the Video element.
