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?
var button = document.getElementById("makeItRed");
button.addEventListener('click',function(){
var warning = document.getElementById("warning");
document.body.style.backgroundColor = 'red';
});
<!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>

But the instructions ask you to "... apply a background color of "red" to the warning div."
