This example shows a minimal HTML page that displays the text “Hello World” in large type, centered on the screen. It demonstrates the integration of CSS for styling and JavaScript for dynamic content manipulation within a static HTML document. The code uses the Document Object Model (DOM) API, specifically `document.getElementById`, to select the `<pre>` element and update its `textContent` property. The page loads a precompiled `bundle.js` script, and the visual styling is defined in a `<style>` block within the HTML head.
