It reflects the src attribute of the <source> element nested in an <audio> or <video> element. It has no meaning and is ignored when it is nested in a <picture> element.

Value

  <source
    id="el"
    src="/firefox/mdn-asset-missing.svg"
    type="video/webp"
    media="screen and (600px <= width <= 800px)" />
</video>

const el = document.getElementById("el");
console.log(el.src); // Output: "large.webp"
el.src = "medium.webp"; // Updates the src value
