This example displays a single line of large, centered text reading “Hey HTML” in a browser. It demonstrates a minimal web page that combines CSS for styling and JavaScript for interactive behavior. The code uses standard HTML elements like `<h1>` and `<style>`, and executes a JavaScript `console.log` command that outputs a message to the browser’s developer tools. The page’s appearance and functionality are defined entirely within a single `index.html` file, with no external data sources or visualization libraries.
