This example presents a minimal web page that displays the text “Hello HTML” in the center of the viewport, styled with a large 13em font size. It demonstrates the foundational structure of an HTML document, including a `<head>` section for metadata and CSS styling, and a `<body>` containing the visible content. The page also includes an inline JavaScript snippet that logs the message “Hello JavaScript!” to the browser’s console, showcasing basic client-side scripting. The implementation relies solely on standard HTML, CSS, and JavaScript without any external libraries.
