Which of the following CSS Property sets the pace of the transition to the next keyframe, as described in the previous section?

animation-timing-function
animation-pace-function
animation-transition-function
none of the mentioned

The correct answer is: A. animation-timing-function

The animation-timing-function CSS property sets the pace of the transition to the next keyframe, as described in the previous section. It takes a function as its value, which can be one of the following:

  • ease: The default value. The animation starts slowly, then speeds up, then slows down again.
  • linear: The animation moves at a constant speed.
  • ease-in: The animation starts slowly, then speeds up.
  • ease-out: The animation starts quickly, then slows down.
  • ease-in-out: The animation starts slowly, then speeds up, then slows down again.
  • step-start: The animation starts at the first keyframe and then jumps to the next keyframe.
  • step-end: The animation starts at the last keyframe and then jumps to the next keyframe.
  • jump-start: The animation starts at the first keyframe and then jumps to the last keyframe.
  • jump-end: The animation starts at the last keyframe and then jumps to the first keyframe.

For example, the following CSS code will cause the element to move from left to right at a constant speed:

“`
.element {
animation: move 2s linear;
}

@keyframes move {
0% {
left: 0;
}
100% {
left: 100%;
}
}
“`

The following CSS code will cause the element to move from left to right, starting slowly, then speeding up, then slowing down again:

“`
.element {
animation: move 2s ease;
}

@keyframes move {
0% {
left: 0;
}
50% {
left: 50%;
}
100% {
left: 100%;
}
}
“`
