This example displays the text “Hello HTML” in large, centered type, styled solely through CSS, while a JavaScript console message logs “Hello JavaScript!”. It is a minimal demonstration of how static HTML content and interactive browser scripting can coexist in a single page. The code uses no external libraries, relying instead on core web APIs such as the Document Object Model and the browser’s built-in console. The rendering approach is straightforward: CSS controls the visual presentation, and JavaScript executes immediately on page load to output its message.
