It is usually a keyword, which can be ease, linear, ease-in, ease-out, or ease-in-out. This will result in an animation that spins first one way and then the other. If all you need is a very simple bounce, it's as easy as just changing the transition function from ease-in to something else, such as a cubic-bezier. The latter can be created using a tool such as this tool by Lea Verou. This will make your element use the keyframes from 0% to 100% for the specified duration then go from 100% to 0% after the first iteration is complete. It is a shorthand for animation-name, animation-duration, animation-timing-function, animation-delay, animation-iteration-count, animation-direction, animation-fill-mode, animation-play-state, and animation-timeline. Default: 1; animation. For more information about Tailwind's responsive design features, check out the Responsive. See full list on blog. The ease-in keyword, which is being used in the previous Codepen example, will set the acceleration to start slowly—easing in.

Identify an animation property that repeats the animation being played without stopping. For keyframed animations, the timing function applies between keyframes rather than over the entire animation. the animation’s easing (or timing function). The linear() easing function is currently implemented in Chromium-based browsers and Firefox. I believe you're looking for animation-direction:alternate, but your question is not very clear. The linear easing function: linear The linear easing function is an identity function meaning that its output progress value is equal to the input progress value for all inputs. What you can do is create your own bezier-curve using a tool like cubic-bezier. You can apply CSS to your Pen from any stylesheet on the web. 6s” refers to the duration of the animation, and “ease-out” is an example of the timing-function to apply. It indicates that the interpolation starts slowly, accelerates sharply, and then slows gradually towards the end. Setting the animation-direction property to alternate provides the second half of the movement. When the mouse stops hovering, the -webkit-animation property returns to its default value (blank), which means that the shake animation is removed, and everything returns to how it.
