find the diff

javascript: (function () {
  const container = document.querySelector("body");
  const img = container.querySelector("img");
  img.style.position = 'absolute';
  const l = img.cloneNode();
  l.style =
    "position: absolute;z-index: 1;left: 0px;bottom: 0px;width: auto;height: auto;transform: scale(0.5) translate(0,50%)";
  const r = img.cloneNode();
  r.style =
    "position: absolute;z-index: 1;bottom: 0px;transform: scale(.5) translate(-561px,50%);mix-blend-mode: difference;width: auto;height: auto;";
  container.appendChild(l);
  container.appendChild(r);
})();
