Hey Brendan Dzeguze,

You should use setTimeout() method for this challenge.

  1. Write down the setTimeout method after function.
  2. Inside the setTimeout parentheses call the startAnimation function along with 2 seconds.

Here's the final code:

const section = document.getElementById("animateMe");

function startAnimation() {
  //Applies spinning animation to section element
    section.className = "spin";
}

setTimeout(startAnimation, 2000);

Hope this helps!
