Understanding WebVTT
WebVTT, or Web Video Text Tracks, is a format used to display timed text tracks for video content on the web. It is a simple and flexible format that allows for the creation of captions, subtitles, and other types of text tracks that can be synchronized with video content.

WebVTT files are typically created using a text editor or specialized software, and are then linked to video content using the HTML5 video element. The cues in the WebVTT file are synchronized with the video content, allowing for the display of captions, subtitles, and other types of text tracks.
What are the benefits of using WebVTT?
WebVTT offers a number of benefits for video content creators and viewers. It allows for the creation of captions and subtitles that can improve accessibility and make video content more inclusive.
