ease - the transition has a slow start, fast middle, then slow end linear - the transition has a consistent speed from start to end ease-in - the transition will have a slow start ease-out - the transition will have a slow end ease-in-out - the transition has a slow start and end cubic-bezier(n,n,n,n) - a customizable transition values that we specify ourselves. It’s handy to use generator tools such as https://cubic-bezier.com/.
