That means we use getBoundingClientRect () on the element that will serve as a proxy for the start state, and divide it with the value from the end state. If you use steps (10) in your animation, it will make sure only 10 keyframes happen in the allotted time. View this demo on the Codrops PlaygroundThis effect is applied by using one of the timing functions described in CSS. The W3Schools online code editor allows you to edit code and view the result in your browserStep 1: Calculate the start and end states. This, in essence, lets you establish an acceleration curve so that the speed of the transition can vary over its duration. Given this, the property transitions from f(i1,i2,…,in) to f(f1,f2,. 第二个参数 start 或 end ，表示阶跃点，. Technically, the implementation would involve transform, transform-origin, animation-timing-function and several more calculations.
