示例1: if

CSSAnimation& aOld,
TimingParams& aNewTiming,
nsTArray<Keyframe>& aNewKeyframes,
bool aNewIsStylePaused,
nsStyleContext* aStyleContext)

// identity (and any expando properties attached to it).

}
// Handle changes in play state. If the animation is idle, however,
// changes to animation-play-state should *not* restart it.
if (aOld.PlayState() != AnimationPlayState::Idle) {
// CSSAnimation takes care of override behavior so that,
// for example, if the author has called pause(), that will
// override the animation-play-state.
// (We should check aNew->IsStylePaused() but that requires
// downcasting to CSSAnimation and we happen to know that
// aNew will only ever be paused by calling PauseFromStyle
// making IsPausedOrPausing synonymous in this case.)

// animation to become irrelevant so only add a changed record if
// the animation is still relevant.
