Help with highlighting a singular list element on click.

this should work for you
const randomDiv = document.querySelector(".random-div");
randomDiv.addEventListener("click", clickHandler);

function clickHandler(e){
const clickDiv = e.target.closest(".click-div");
const currentActive = e.currentTarget.querySelector(".active");
if(currentActive) currentActive.classList.remove("active");
clickDiv.classList.add("active");
}
const randomDiv = document.querySelector(".random-div");
randomDiv.addEventListener("click", clickHandler);

function clickHandler(e){
const clickDiv = e.target.closest(".click-div");
const currentActive = e.currentTarget.querySelector(".active");
if(currentActive) currentActive.classList.remove("active");
clickDiv.classList.add("active");
}
