A Bezier curve is a mathematically defined curve used in two-dimensional graphic applications like adobe illustrator, Inkscape, etc. The curve is defined by four points: the initial position and the terminating position i.e P0 and P3 respectively (which are called “anchors”) and two separate middle points i.e P1 and P2(which are called “handles”) in our example. Bezier curves are frequently used in computer graphics, animation, modeling, etc. Syntax: cubic-bezier( x1, y1, x2, y2 )Parameters: This function accepts four parameters that are mandatory. It contains a numeric value and the value of x1 and x2 lies between 0 to 1.
