Mathematical CSS Animations with Polar Coordinates
This spiral animation uses a clever combination of CSS transforms to create
a mathematical spiral pattern. Each particle follows the same path but starts
at a different time using animation-delay.
The magic happens because translateX() moves the element along
its current rotated axis. As we rotate AND translate simultaneously, the
element traces a spiral path through 2D space.
Try modifying the --spiral-radius, --spiral-duration,
or rotation values in the CSS to create different spiral patterns!
