This example shows a minimal web page that renders the text “Hello HTML” in large, centered type using a 13em font size. It demonstrates the foundational structure of an HTML document, including a `<head>` section with embedded CSS styling and a `<body>` containing the text content. The page uses no external libraries or JavaScript, relying solely on plain HTML and CSS to achieve its visual output. It serves as a starting point for understanding how to build and style basic web content.
