source class final

The <source> HTML element specifies multiple media resources for the <picture>, the <audio> element, or the <video> element. It is an empty element, meaning that it has no content and does not have a closing tag. It is commonly used to offer the same media content in multiple file formats in order to provide compatibility with a broad range of browsers given their differing support for image file formats and media file formats.
