4 JavaScript Bounce Effects

This Elastic Animated Star Rating component turns a mundane feedback form into a delightful micro-interaction. Instead of simple color changes, the stars spring to life with a satisfying “elastic” pop when clicked. The animation logic handles both filling (bouncing in) and emptying (shrinking away) states, making the interaction feel physically responsive and engaging. (Requires: GSAP)

This Bouncy Digital Block Clock transforms a standard time display into a playful, tactile UI element. It utilizes a split-digit technique where numbers “roll” into place while their container physically bounces, adding weight and character to every second that passes. The component is fully responsive, supports system dark mode automatically, and ensures accessibility via dynamic ARIA labels.

This GSAP CustomBounce Loader demonstrates how to inject personality into a standard waiting state using cartoon physics. It depicts a kinetic chain reaction: a “driver” dot hits a line of idle dots, causing them to jump, squash, and stretch. This example showcases the power of GreenSock’s CustomBounce plugin to create realistic (yet stylized) material deformations. (Requires: GSAP, CustomBounce, CustomEase)

A playful SVG pagination component animated with GSAP. JavaScript dynamically generates color-coded rings and orchestrates a physics-based ‘jump’ animation where the active dot squashes, stretches, and arcs parabolically to its new position, changing color in mid-air.
