This example displays the text “Hello HTML” prominently in the center of the page, styled with a very large font size and centered alignment via CSS. It demonstrates a minimal HTML page that integrates CSS for visual styling and JavaScript for interactivity. The JavaScript code logs “Hello JavaScript!” to the browser’s console, requiring the user to open developer tools to observe this output. The example does not use any external libraries or frameworks, relying solely on the native DOM and browser APIs.
