  height: 100px;
  background-color: red;
  transition: opacity 1s;
}

target.addEventListener("click", () => (target.style.opacity = "0"));
target.addEventListener("transitionend", () => target.remove());

to set the div’s opacity to 0.

After the transition is done, we remove the div with remove.
