-    The non-step keyword values (ease, linear, ease-in-out, etc.) each represent cubic Bézier curve with fixed four point values, with the cubic-bezier() function value allowing for a non-predefined value. The step easing functions divides the input time into a specified number of intervals that are equal in length. It is defined by a number of steps and a step position.
