What are "cubic-bezier" and its values in "transition-timing-function" in CSS?!

Question

Is there anybody who can describe me the following syntax?!
transition-timing-function:cubic-bezier(0,0,1,1);
I don't know anything about the values of cubic-bezier?!

Answer 1

The <single-transition-timing-function> CSS data type denotes a mathematical function that describes how fast one-dimensional values change during animations. This lets you vary the animation's speed over the course of its duration.

Answer 2

Thanks Shudarshan! But I don't understand the definition and role of each number in paranthesis!
