This example shows a static web page that displays the text “Hello HTML!” centered on the screen. The code defines a single `div` element with the class `message`, styled using a CSS rule that sets the font size to 13em and aligns the text to the center. No JavaScript or external libraries are used; the page renders solely through the browser’s default HTML and CSS rendering engine. The project serves as a minimal illustration of how to structure a basic HTML document with embedded styles.
