Galaxy Vortex
A conic-gradient vortex swirls slowly behind the X at rest, then accelerates dramatically on hover — the ultimate premium "this is special" close button.
Galaxy Vortex the 18th of 18 designs in the 18 CSS Close Buttons collection. The design is implemented in pure CSS — no JavaScript required. Copy the HTML and CSS panels below into your project. Because the demo is pure CSS, it works in any framework or templating engine you happen to use. The design honours prefers-reduced-motion and uses real semantic markup, so it ships accessibility-ready out of the box.
