In CSS3, you can use the "animation-timing-function" attribute to set the animation rotation speed. This attribute is used to specify how the animation will complete a cycle and set the speed curve of the animation. The syntax is "element {animation- timing-function:speed attribute value;}".
The operating environment of this tutorial: Windows 10 system, CSS3&&HTML5 version, Dell G3 computer.
animation-timing-function specifies how the animation will complete a cycle.
The speed curve defines how long it takes for the animation to change from one set of CSS styles to another.
Speed curve is used to make changes smoother.
Default value: ease
The syntax is:
animation-timing-function: value;
The mathematical function used by animation-timing-function is called cubic Bezier curve, speed curve. With this function, you can use your own values, or use one of the predefined values:
Property values are as follows:
linear The speed of the animation from start to end Are the same. Test
ease Default. The animation starts at a slow speed, then speeds up, then slows down before ending. Test
ease-in The animation starts at a slow speed. Test
ease-out The animation ends at a slow speed. Test
ease-in-out The animation starts and ends at a slow speed. Test
steps(int,start|end) specifies the number of intervals (steps) in the time function. There are two parameters. The first parameter specifies the number of intervals of the function, which is a positive integer (greater than 0). The second parameter is optional and indicates whether the animation is continuous from the beginning or end of the time period. The meanings are as follows: start: means to start directly. end: Default value, indicating an abrupt end.
cubic-bezier(n,n,n,n) The own value in the cubic-bezier function. Possible values are numeric values from 0 to 1.
The example is as follows:
