This example demonstrates a minimal HTML page that uses CSS and JavaScript to render a centered message. The page displays the text “Hello HTML!” in a large, bold font using an inline style with a `.message` class set to a font size of 13em. The code relies on standard HTML elements, an embedded `<style>` block for styling, and no external JavaScript libraries or frameworks. React is not used despite the metadata, and the visualization is static with no data or interaction.
