This SVG example explores shape, color, and interactivity using custom paths and CSS transitions. A stylized funnel shape is rendered with a multi-stop linear gradient defined in SVG `<defs>`, creating a banded color effect. The page also includes a heart path with a dashed stroke that animates its offset on hover via CSS `transition`. Additional CSS demonstrates hover effects on a hidden division. The example uses plain SVG elements and CSS styling, including the `stroke-dasharray` and `stroke-dashoffset` properties for path animation.
