JavaScript Interacting with the DOM Responding to Events Adding an Event Listener

In the button click handler, apply a background color of "red" to the warning div.

I am getting an error message saying the background doesn't turn red when the button is clicked even though I do get a red background when the button is clicked. What am I doing wrong?

app.js
var button = document.getElementById("makeItRed");
button.addEventListener('click',function(){
  var warning = document.getElementById("warning");
  document.body.style.backgroundColor = 'red';
});
index.html
<!DOCTYPE html>
<html>
    <head>
        <title>Adding an Event Listener</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="warning">
            Warning: My background should be red!
        </div>
        <button id="makeItRed">Make It Red!</button>
        <script src="app.js"></script>
    </body>
</html>

This code applies the red background to the entire document body.
But the instructions ask you to "... apply a background color of "red" to the warning div."
