This example presents a minimal HTML page that displays the text “Hello HTML!” prominently centered on the screen. It demonstrates the fundamental integration of CSS for styling and JavaScript for potential interactivity, though no scripts are actually used in the code. The page uses a `.message` class with a large font size and text alignment, rendered directly in the browser’s DOM without any external libraries or frameworks. The data source is static text embedded in the markup, and the rendering relies entirely on native HTML and CSS, with no canvas, SVG, or JavaScript APIs involved.
