This example displays a large, centered HTML greeting message using plain HTML and CSS, with the text "Hello :) HTML" styled at an oversized font size. The page includes a script that logs "Hello JavaScript!" to the browser’s developer console upon loading. It uses no external libraries or data sources, relying solely on the native DOM and inline `<style>` and `<script>` elements. The rendering approach is basic static HTML, demonstrating a minimal setup for a web page.
