animation의 시작 중간 끝의 상태를 정의 한다.
ex)
@keyframes moveBox {
from {
border-radius: 0;
left: 0;
background-color: blue;
transform: scale(1);
}
to {
border-radius: 50%;
left: calc(100% - 100px);
background-color: green;
transform: scale(0.75);
}
}
위의 예시처럼 시작을 from 끝을 to로 작성할수있고
더욱 세밀한 움직임을 표현 할경우 %를 사용할수있다.
animation: name duration timing-function delay iteration-count direction
animation-name : 어떤 keyframes를 적용할건지
animation-duration : animation 작동 시간
animation-timing-function : anmation 재생 패턴
animation-delay : 지연
animation-iteration-count : animation 재생 횟수
animation-direction : animation 재생 방향
ex)
<div class="container">
<div class="item">
<span>item</span>
</div>
</div>
.container {
width: 100%;
height: 104px;

}
.item {

height: 100px;
background-color: blue;
display: flex;
flex-direction: row;
justify-content: center;
align-items: center;
