This example shows a single, static message, “Hello HTML!”, displayed prominently in the center of the page. It demonstrates the foundational structure of a web page using HTML, CSS, and JavaScript, with the text styled via a CSS class that sets a large font size. The implementation is a bare-bones HTML file, containing a `<style>` block for presentation and a `<div>` element for content, intended as a starting point for more complex projects. It does not use any JavaScript libraries or data sources.
