Data-driven tag cloud component with proportional typography scaling and colorful inset box-shadow hover effects

Dynamic Data-Driven Tag Cloud Component

This is a Dynamic Data-Driven Tag Cloud Component. It consumes an external JSON payload to generate interactive tags, proportionally scaling their font sizes based on their frequency of use. Its function is to visually prioritize popular categories, allowing users to intuitively navigate heavy content taxonomies without reading numbers.

Animated interface switching between card and list layouts using the FLIP technique to smoothly interpolate element positions and scales.

FLIP Animated Responsive Grid Switcher

This is an Animated FLIP Grid Switcher. It bridges the gap between two distinct visual states — Card and List — by mathematically calculating the delta of motion. The component ensures that interface elements do not simply “jump” during a layout change but glide organically into their new coordinates, maintaining spatial continuity for the user.

GSAP ScrollTrigger List Expansion

This snippet showcases a GSAP ScrollTrigger List Expansion effect. It mimics the native iOS “Notification Center” or “Wallet” card stack behavior. Its function is to condense a long list of items into a compact, layered visual stack, and then fluidly expand them into full, scrollable cards as the user scrolls down the container, creating a highly tactile mobile UI experience. (Requires: GSAP, ScrollTrigger)

Interactive list where a clicked gray item expands into a large purple detailed card with a smooth animated transition of the avatar and text lines

GSAP Flip Layout Expansion

This GSAP Flip Layout Expansion demonstrates how to animate complex layout changes that are usually impossible with pure CSS. By utilizing the FLIP (First, Last, Invert, Play) technique via GSAP, a list item transforms from a horizontal row into a vertical, detailed card. It smoothly handles the resizing of nested elements (like the avatar) and the repositioning of surrounding items without jumpy reflows. (Requires: GSAP, GSAP Flip Plugin)
