When you specify CSS styles inside the @keyframes rule, the animation will gradually change from the current style to the updated style at specific times.
The animation will always be bound to a specified element or elements.
The following has a “from” frame and “to” frame, which are essential a start and end.
/* the element to animate */
div {
width: 20px;
height: 120px;
background-color: red;
opacity: 1.0;
position: relative;
top: 0;
left: 0;
animation-name: move-div;
animation-delay: 2s;
animation-duration: 3s;
animation-iteration-count: 4;
}
/* the animation */
@keyframes move-div {
from {
left: 0;
opacity: 1.0;
}
to {
left: 300px;
opacity: 0;
}
}
Reload the page, and the following element will wait 2 seconds and then animate over 3 seconds, 4 times.
We can also use percentages to set multiple frames to change the animation multiple times.
In the following, we have three frames. The first is the starting point which animates to a midpoint and then to an endpoint. And because we have the animation-iteration-count set to infinite, it starts back over again and never stops.
/* the element to animate */
div {
width: 20px;
height: 120px;
background-color: red;
opacity: 1.0;
position: relative;
top: 0;
left: 0;
animation-name: ping-pong;
animation-duration: 3s;
animation-iteration-count: infinite;
}
/* the animation */
@keyframes ping-pong {
0% {
left: 0;
background-color: red;
}
50% {
left: 95%;
background-color: blue;
}
100% {
left: 0;
background-color: red;
}
}
The following element will bounce from left to right and back to left again infinite times while changing colors.
