This example demonstrates a minimal web page that displays the text “Hello HTML!” centered and enlarged with CSS. The page renders a single message using an HTML `<div>` element, styled through a CSS class that sets font size and text alignment. It uses no external libraries or data sources, relying solely on static HTML markup and inline CSS within a `<style>` block. The JavaScript is not utilized, making this a pure HTML and CSS demonstration of basic document structure and styling.
