This example displays the text “Hello HTML” in a large, centered layout using CSS styling and outputs “Hello JavaScript!” to the browser’s developer console. It demonstrates a minimal HTML page that combines inline CSS for presentation with a JavaScript script tag for basic interactivity. The page also includes a separate `tes.js` file containing a variable assignment, though it is not referenced or executed. The code relies on standard HTML, CSS, and JavaScript APIs without any external libraries or data sources.
