This example demonstrates a minimal HTML page that renders a centered message reading "Hello HTML!" with large, CSS-styled text. It serves as a barebones starter template, showcasing the integration of HTML structure, CSS styling, and JavaScript support within a single file. The page uses a simple `<div>` element with a class that applies a font size of 13em and text alignment via CSS. No external libraries or JavaScript APIs are invoked; the code relies solely on native web standards.
