A sunrise animation built with SVG and CSS keyframes, shows a sun rising over a mountain range against a gradient sky. The scene uses a linear gradient for the sky, a radial gradient for the sun, and a path for the mountains. The CSS animations `rise`, `sky-gradient`, and `fade-in` transition the sun’s position, the sky’s gradient colors, and the mountains’ opacity. Both the gradient and shape definitions are handled directly in SVG markup, with no JavaScript libraries.
