A single HTML page uses CSS animations to depict a sunrise over the sea, with the text "Hello" and "HTML" scaling and rising as the background shifts from dark navy to sky blue and the text color changes from red to yellow. The example relies entirely on standard HTML and CSS, including the `@keyframes` rule and the `animation-name` and `animation-duration` properties applied to the `body` and `message` elements. No JavaScript libraries or data sources are involved; it is a self-contained demonstration of pure CSS-based visual effects.
