An animation lets an element gradually change from one style to another.
/* The animation code */
@keyframes example {
from {background-color: red;}
to {background-color: yellow;}
}
/* The element to apply the animation to */
div {
width: 100px;
height: 100px;
background-color: red;
animation-name: example;
animation-duration: 4s;
}
/* The animation code */
@keyframes example {
0% {background-color: red;}
25% {background-color: yellow;}
50% {background-color: blue;}
100% {background-color: green;}
}
/* The animation code */
@keyframes example {
0% {background-color: red; left:0px; top:0px;}
25% {background-color: yellow; left:200px; top:0px;}
50% {background-color: blue; left:200px; top:200px;}
75% {background-color: green; left:0px; top:200px;}
100% {background-color: red; left:0px; top:0px;}
}
Delay an Animation
div {
width: 100px;
height: 100px;
position: relative;
background-color: red;
animation-name: example;
animation-duration: 4s;
animation-delay: 2s;
}
Set How Many Times an Animation Should Run
div {
width: 100px;
height: 100px;
position: relative;
background-color: red;
animation-name: example;
animation-duration: 4s;
animation-iteration-count: 3;
}
use the value “infinite” to make the animation continue for ever
Run Animation in Reverse Direction or Alternate Cycles
div {
width: 100px;
height: 100px;
position: relative;
background-color: red;
animation-name: example;
animation-duration: 4s;
animation-iteration-count: 3;
animation-direction: reverse;
}
div {
width: 100px;
height: 100px;
position: relative;
background-color: red;
animation-name: example;
animation-duration: 4s;
animation-iteration-count: 3;
animation-direction: alternate;
}
Specify the Speed Curve of the Animation
#div1 {animation-timing-function: linear;}
#div2 {animation-timing-function: ease;}
#div3 {animation-timing-function: ease-in;}
#div4 {animation-timing-function: ease-out;}
#div5 {animation-timing-function: ease-in-out;}
