What are the parameters of css3 Bezier curve function
This article mainly explains "what are the parameters of css3 Bezier curve function". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "what are the parameters of the css3 Bezier curve function"!
The css3 Bezier curve function cubic-bezier () has four parameters that specify the coordinates of the middle points of the curve that are separated from each other. The syntax is "cubic-bezier". The values of parameters x1, y1, x2, and y2 range from 0 to 1.
The operating environment of this tutorial: windows7 system, CSS3&&HTML5 version, Dell G3 computer.
Css3 Bezier curve (cubic-bezier)
Cubic-bezier, also known as cubic Bezier, is mainly a function of generating velocity curves (Bezier curves) for animation. It is an important value in animation-timing-function and transition-timing-function.
Syntax:
Cubic-bezier (x1 ~ y1 ~ x2 ~ 2)
Let's look at the picture and say:
From the figure above, we can clearly know the value range of cubic-bezier:
P0: default value (0c0)
P1: value (x1jue y1)
P2: value (x2jiny2)
P3: default value (1Phone1)
In cubic-bezier, p0 and p3 are the default points, so we only need to define p1 and p2. At the same time, the values of x1, y1, x2, and y2 are in the range of [0Power1].
Note: when the value is out of range, the cubic-bezier will fail.
There are several commonly used fixed values in CSS3 animation.
Ease: cubic-bezier (.25, .1, .25,1)
Linear: cubic-bezier (0,0,1,1)
Ease-in:cubic-bezier (.42pm 0pm 1pm 1)
Ease-out:cubic-bezier (0pd0.58pr 1)
