< PICTURE >
The <picture> element works similar to the <video> and <audio> elements. You set up different sources, and the first source that fits the preferences is the one being used
< VIDEO >
The controls attribute adds video controls, like play, pause, and volume.
It is a good idea to always include width and height attributes. If height and width are not set, the page might flicker while the video loads.
The <source> element allows you to specify alternative video files which the browser may choose from. The browser will use the first recognized format.
The text between the <video> and </video> tags will only be displayed in browsers that do not support the <video> element.
