This example demonstrates a minimal web page that combines HTML, CSS, and JavaScript in a single file. It displays the text "Hello HTML" in large, centered type styled through inline CSS, while JavaScript logs "Hello JavaScript!" to the browser’s console via `console.log`. No external libraries or data sources are used; the page relies solely on native browser APIs and static markup. The code serves as a bare-bones starting point for web development, illustrating the separation of structure, presentation, and behavior.
