Effeckt.css
A Performant Transitions and Animations Library
...The project focuses on practical details such as using compositing-friendly properties, keeping DOM structures lean, and providing hooks so JavaScript can toggle classes without micromanaging animation state. Each effect is isolated, documented, and demoed, allowing designers to copy just what they need rather than dragging in a monolithic framework. By standardizing names and behaviors, it helps teams keep motion design consistent across a product while remaining easy to theme. The library doubled as a learning resource during the rise of CSS animations, showing how to achieve polished interactions without heavy JavaScript.
