<source>
element.
The <source>
HTML element specifies multiple media resources for the picture
, the audio
element, or the video
element. It is a void 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.
