This example demonstrates a minimal webpage that displays the text “Hello HTML!” centered on the screen. The page uses plain HTML and CSS to structure and style the message, with the `.message` class setting a large font size and text alignment. It also includes a JavaScript file via an HTML script tag, though the displayed content itself relies solely on the markup and stylesheet. The code defines a single `div` element containing the greeting, showing how basic styling and static content can be rendered in a browser without external libraries.
