A minimalist demonstration of the fundamental building blocks of web development, this example displays a single line of static text, “Hello HTML,” centered on the page using CSS. The page also logs the string “Hello ES6” to the browser console via JavaScript. The code defines a styled HTML document that uses a plain `style` tag for layout and an inline `script` tag to execute console output, showcasing basic interaction between HTML, CSS, and JavaScript without any external libraries or dynamic data.
