Ti permette di definire una curva di accelerazione, in modo che la velocità della transizione possa variare nell'arco della sua durata.</p> + +<p>Questa curva di accelerazione viene definita utilizzando uno {{cssxref("<timing-function>")}} per ogni proprietà che ottiene una transizione.</p> + +<p>È possibile specificare un numero arbitrario di funzioni di temporizzazione; ciasuna di queste sarà applicata alla corrispondente proprietà seguendo le specifiche in {{ cssxref("transition-property") }}, dove in questo caso si comporta come la lista principale.</p> + +<p>Se ci sono meno funzione specificate rispetto alle proprietà presenti nella lista, i valori mancanti saranno impostati a quello iniziale (<code>ease</code>).
