This example shows a simple “Hello HTML!” message centered on the page using large, bold text. Rendered entirely through static HTML and CSS, it relies on a `<style>` block to set the font size and alignment via the `text-align` property on a `div` with the class `message`. No JavaScript libraries, data sources, or interactive behavior are present; the visualization demonstrates the minimal structure required for a standalone web page. The code uses core HTML elements and CSS styling only.
