This example demonstrates a minimal HTML page that combines CSS and JavaScript, rendering the text "Hello HTML" at a massive scale using an inline style of 13em. It shows how a bare-bones web document can integrate styling and scripting without external libraries or frameworks. The code uses the Document Object Model (DOM) via `index.html` structure, applies CSS through a `<style>` block, and executes a `console.log` statement in JavaScript to output "Hello JavaScript!" to the browser's developer tools. It serves as a foundational template for understanding static page composition.
