Easing functions may be specified on individual keyframes in a @keyframes rule. ) each represent cubic Bézier curve with fixed four point values, with the cubic-bezier() function value allowing for a non-predefined value. /* @keyframes duration | timing-function | delay |. As with transitions, the choice of timing function can greatly impact the feel of an animation. Also useful to see the animation short-hand docs to set all the properties at once (like your code does)Conclusion. Then I have an animation with a set of keyframes for how far along that animation should be at each phase of the animation: @keyframes circlePath { 0% { offset-distance: 0%; } 10% { offset-distance: 8. animate { background. The animation-timing-function CSS property sets how an animation progresses through the duration of each cycle. reverse is an essential tool of preventing code duplication, however with the timing function behaving differently it is less useful than it could be. This, in essence, lets you establish an acceleration curve so that the speed of the transition can vary over its duration. This module is used by Animated. ease-in. For keyframed animations, the timing function applies between keyframes rather than over the entire animation. It is similar to the ease-in-out keyword, though it accelerates more sharply at the beginning. But multi-step-spin breaks it into 4 distinct steps, and each step has the timing function applied:Define the animation.
