This example presents a minimal HTML page that displays a large, centered message reading “Hello HTML!” The page pairs a plain HTML structure with a linked CSS stylesheet, while a separate JavaScript module logs “hello world” to the browser console. The code relies on fundamental web technologies—HTML elements, CSS properties like `font-size` and `text-align`, and the JavaScript `console.log` API—to demonstrate the basic separation of structure, style, and behavior. It serves as a bare-bones starting point for understanding how these core languages interact in a simple rendered page.
