A typical CSS animation is made up of two parts: An element (or elements) styled with the animation declaration where we specify details of the animation sequence like the keyframes to use, duration, timing function, play mode, and more; The @keyframes rule where we specify the actual appearance of our element at each moment in time1 Answer. CSS transitions let you decide which properties to animate (by listing them explicitly), when the animation will start (by setting a delay), how long the transition will last (by setting a duration), and how the transition will run (by defining an easing function, e. If you would move a variable called x from 0 to 400 pixels in 750. In this example, using groups both on enter and leave allows for two different timing configurations. At the instants it is called, x and t both say what the time is now, relative to the start of the animation. Duration is all about timing, and timing has a big impact on the movement’s naturalness. Vue. In the next chapter, we’ll take a closer look at how timing functions work with CSS @keyframes. We apply the animation with described keyframes to the desired element using the animation property. some-element { transition: 1s linear; }17.
