This is a minimal HTML starter example that displays the static text “Hello HTML!” in a large, centered font. It demonstrates the fundamental web development stack of HTML for structure, CSS for styling, and JavaScript for interactivity. The code uses an inline `<style>` block to set the `font-size` and `text-align` of a CSS class, while the `<div>` element contains the message. No JavaScript or external libraries are present in the rendering; the page only shows a styled text output without dynamic behavior or data visualization.
