This example demonstrates a minimal HTML page that displays a large, centered text message reading “Hello HTML!” using a CSS class for styling. The page contains no JavaScript logic or external dependencies, relying solely on static HTML structure and inline CSS within a `<style>` block to control font size and alignment. It serves as a bare-bones starter template, illustrating the foundational trio of web technologies—HTML for content, CSS for presentation, and the optional inclusion of JavaScript for interactivity, which is not utilized here. The rendering approach is standard browser HTML parsing and layout.
