This example displays a minimal HTML page that renders the text “Hello HTML” in the center of the browser window. It uses CSS inline styles to set the font size to an extremely large 13em and the text alignment to center. The page also executes a JavaScript script that logs the message “Hello JavaScript!” to the developer console. The example demonstrates the fundamental structure of an HTML document, including the `<head>`, `<style>`, and `<script>` elements, and serves as a bare-bones starting point for web development.
