<body>
<div class="container">
<h1>Change Background Color</h1>
<button id="colorBtn">Change Color</button>
</div>
<script src="script.js"></script>
</body>
</html>
CSS Styling:
body {
font-family: Arial, sans-serif;
background-color: #f0f0f0;
margin: 0;
padding: 0;
}
.container {
text-align: center;
margin-top: 100px;
}

}
button {
padding: 10px 20px;
background-color: #007bff;

}

}
JavaScript Code:
// Get the button element
const colorBtn = document.getElementById('colorBtn');
// Add click event listener to the button
colorBtn.addEventListener('click', () => {
// Generate a random color
const randomColor = '#' + Math.floor(Math.random()*16777215).toString(16);
// Change the background color of the body
document.body.style.backgroundColor = randomColor;
});
Output:-
JavaScript code to change the background color when the button is clicked.
