Smooth as Butter: Achieving 60 FPS Animations with CSS3
José Rosário

In the last demo, you remove `.menu — animatable` when `transitionend`. I guess it’s for performance but i don’t know why since that class only has a `transition` attribute and it’ll be added back when click. Could you please tell me some detail or give me some keywords to searching for.
