1 JavaScript 3D Flip Effect

This demonstration is focused on various ways to implement the Flip Effect, which is applied to two-sided UI elements. The main technical focus is on utilizing the CSS properties transform: rotateY(180deg) and perspective to create a realistic 3D space.

You’ll see how minimal JavaScript is used purely to manage the flip state (adding/removing a class), allowing all resource-intensive animation to be offloaded to the GPU. This is an elegant and performant way to add striking interactivity without resorting to heavy third-party libraries.

3D Page Fold Transition (FLIP Principle)

An elegant implementation of the FLIP animation principle to create a stunning shared element transition between two views, where JS calculates the positions and CSS performs the inverse transform for a smooth change.
