SVG Fundamentals
This example presents a minimal HTML page that demonstrates the relationship between HTML, CSS, and JavaScript in a browser context. The page displays a large, centered "Hello HTML!" message styled with a CSS rule in a `<style>` block, using a `div` element with a custom `message` class. No JavaScript libraries or data sources are involved; the rendering relies solely on native HTML and CSS. The code highlights how static content and styling can be combined without external frameworks or interactive visualization components.
