HTML Video
The <video> element puts video on a page. Add controls when visitors should be able to play, pause, and change the volume. You can provide a video file with src or use <source> elements. The poster attribute can show an image before the video starts. Videos should also consider captions. The <track> element can provide subtitles or captions for people who cannot hear the audio and for people who prefer to read.
