<declaranime /> is tiny library for creating html animations in declarative (html) way. It is built on top of GSAP and Google Polymer libraries. More precisely, <declaranime /> is just a simple wrapper around GSAP thus all real cool animation algorithms and logic are handled by GSAP.
<declaranime /> was born as a hobby "side effect" to other hobby project and that's why it is built on top of these technologies. Because project size was never concern, <declaranime /> uses TweenMax and TimelineMax libraries as default animation "providers". If file size concerns you, you can modify "declaranime.html" file and use TweenLite and TimelineLite with desired plugins.
