interpolare con variazione in entrata(To modify how the property value changes as time approaches the keyframe. A value of 100% would make the property change slow down as time approached the keyframe)
interpolare con variazione in uscita(To modify how the property value changes as time moves away from the keyframe. A value of 100% would make the property change start slowly as time left the keyframe)
funzione di interpolazione(A mathematical formula to produce more realistic animations. For example, an easing function can be used to create objects that bounce or spring realistically)
