SVG Fundamentals
This example demonstrates the foundational relationship between HTML, CSS, and JavaScript in a web page, showing a large styled text message. It uses an inline `<style>` block to set the font size and alignment of a `div` element, while the body contains only static markup. No external libraries or APIs are imported, and no JavaScript logic appears, so the page simply renders the text "Hello HTML!" without interaction or data binding. The rendering approach is plain browser defaults for CSS layout and typography.
