Front End Web Development Techdegree Graduate 29,367 PointsHow to change background color using JavaScript
It doesn't work. It doesn't say why. Any ideas what I'm doing wrong?
var warning = document.getElementById("warning");
var button = document.getElementById('makeItRed');
button.addEventListener('click', () => {
warning.style.background-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>
