This example displays the text “Hello HTML” at a massive font size, centered in the browser window. The page loads inline CSS to set body text alignment and font size, while a JavaScript script runs on load to log "Hello JavaScript!" to the developer console. The code uses plain HTML elements, CSS styling rules, and a raw console.log call without any external libraries or frameworks. It demonstrates a minimal static page with client-side scripting, showing how CSS controls layout and JavaScript executes immediately in the browser.
