Animatable – A Gallery Of CSS Transitions
Transitions in CSS3 brings many possibilities on animating and morphing HTML elements.
Lea Verou is sharing a beautiful experiment and resource –Animatable– that showcases different CSS transitions (and how simple they are).
Each transition is applied to a box where you can activate by hovering them (or run the transitions for all items).
You can also click the items to easily see the "from" and "to" values of CSS properties changed.
