This example displays the text “Hello HTML” in large, centered type on a plain page, serving as a minimal demonstration of web fundamentals. It uses a simple CSS `body` style rule for layout and typography, while an inline JavaScript `console.log` statement outputs “Hello JavaScript!” to the browser’s developer console. The page is a bare-bones HTML document, with no external libraries or frameworks, illustrating the core structure of an HTML file, CSS styling, and client-side scripting in a single, self-contained file.
