问题描述
我需要做一个动画逐帧改变一个元素的背景位置。我需要这样做没有宽松或线性动画，只是改变背景位置。是否可以用css3动画实现？
I need to do an animation frame-by-frame changing a background-position of an element. I need to do this WITHOUT easing or linear animation, just changing the background-position. Is it possible to achieve with css3 animation?
谢谢！
推荐答案
是的，它是通过新的step-function缓动的曲线属性。
Yes it is via the new step-function easing curves property.
使用step-start或step-end而不是ease-in等，这将使转换瞬间发生在开始或结束
Instead of "ease-in" etc. use "step-start" or "step-end" which will make the transition happen instantaneously either at the beginning or end of the time period specified in transition-duration.
您还可以有多个步骤：steps（N，start | end]），这将导致转换同样发生间隔的步骤。
You can also have multiple steps: "steps(N, start | end ])" which will have the transition happen in equally spaced steps.
AFAIK这项功能目前仅支援Chrome。
AFAIK this is only supported in Chrome to date.
