There are two technologies here, though both sometimes use the word "animation" they're separate: they implemented transitions in 2007 (using transition-* properties [0]), transitions are used to smoothly go from one state to an other and they are implicit: you only say which CSS property will transition and over which duration and the browser will handle all the decisions within that scope. CSS animations[1] were added in 2009[2]. They are related to transitions but they're explicit and keyframe-based. Much more complex, but much more flexible as well (for instance you can have back and forth movements with animations, but not with transitions).
