Source Code

Copy the source code provided below and set up your project files accordingly. First, create a file named index.html and paste the HTML code into it. Next, create a file called styles.css and insert the CSS code there. Finally, create a file named script.js and paste the JavaScript code into it. This structure organizes your project into separate files for HTML, CSS, and JavaScript, making it easier to manage and maintain your code.
