The HTMLSourceElement interface provides special properties (beyond the regular HTMLElement object interface it also has available to it by inheritance) for manipulating <source> elements.

Properties

HTMLSourceElement.keySystem
Is a DOMString describing the key system encrypting the stream.
HTMLSourceElement.media

HTMLSourceElement.sizes
Is a DOMString representing image sizes between breakpoints
HTMLSourceElement.src
Is a DOMString reflecting the src HTML attribute, containing the URL for the media resource. The HTMLSourceElement.src property has a meaning only when the associated <source> element is nested in a media element that is a <video> or an <audio> element. It has no meaning and is ignored when it is nested in a <picture> element.
HTMLSourceElement.srcset
Is a DOMString reflecting the srcset HTML attribute, containing a list of candidate images, separated by a comma (',', U+002C COMMA). A candidate image is a URL followed by a 'w' with the width of the images, or an 'x' followed by the pixel density.
