Front End Web Development Techdegree Graduate 33,856 PointsI can't seem to be able to apply background-color without re-value the warning const.
const warning = document.getElementById("warning");
let button = document.querySelector('#makeItRed');
button.addEventListener('click', () => {
warning.style.backgound-color = '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>

Treehouse TeacherHi there, Osman! I know that it can be tempting to think that you should use "background-color" because that's how we write it in CSS, right? But in JavaScript, what you're looking for is style.backgroundColor
.
Hope this helps!

Also, you're missing the letter "r" in the name.
So instead of "backgound-color", you should write: "backgroundColor".
