일반적인 CSS 스타일

10. 맞춤형 애니메이션

　1) 키프레임（키프레임)

을 키프레임이라고 하는데 플래시의 키프레임과 비슷합니다.

CSS3에서는 주로 "@keyframes"로 시작하고 그 뒤에 애니메이션 이름과 중괄호 쌍 "{...}"이 옵니다. 괄호 안에는 다양한 기간에 대한 몇 가지 스타일 규칙이 있습니다.

구문: @keyframes animationname {keyframes-selector {css-styles;}}

　animationname: 애니메이션의 이름을 정의합니다.

　keyframes-selector: 변경이 발생하는 시간을 백분율로 지정하거나 0%와 100%에 해당하는 "from" 및 "to" 키워드를 통해 지정합니다. 퍼센트 선택기를 정의하는 것이 좋습니다.

　css-styles: @keyframes 규칙을 사용하면 한 CSS 스타일 세트를 다른 CSS 스타일 세트로 점진적으로 변경하고 이 CSS 스타일 세트를 여러 번 변경할 수 있는 애니메이션을 만들 수 있습니다.

호환성: 현재 브라우저는 @keyframes 규칙을 지원하지 않으므로 "-moz-", "-o-", "-webkit-" 접두사를 추가해야 합니다.

예: 

<span style="color: #800000;">@-webkit-keyframes FromLeftToRight</span>{   <span style="color: #008000;">/*</span><span style="color: #008000;"> Safari 和 Chrome </span><span style="color: #008000;">*/</span><span style="color: #ff0000;">
    0% {left</span>:<span style="color: #0000ff;">0</span>;}<span style="color: #800000;">
    100% </span>{<span style="color: #ff0000;">left</span>:<span style="color: #0000ff;">800px</span>;}<span style="color: #800000;"> 
}
@-moz-keyframes FromLeftToRight</span>{    <span style="color: #008000;">/*</span><span style="color: #008000;"> Firefox </span><span style="color: #008000;">*/</span><span style="color: #ff0000;">
    0% {left</span>:<span style="color: #0000ff;">0</span>;}<span style="color: #800000;">
    100% </span>{<span style="color: #ff0000;">left</span>:<span style="color: #0000ff;">800px</span>;}<span style="color: #800000;"> 
}
@-o-keyframes FromLeftToRight</span>{      <span style="color: #008000;">/*</span><span style="color: #008000;"> Opera </span><span style="color: #008000;">*/</span><span style="color: #ff0000;">
    0% {left</span>:<span style="color: #0000ff;">0</span>;}<span style="color: #800000;">
    100% </span>{<span style="color: #ff0000;">left</span>:<span style="color: #0000ff;">800px</span>;}<span style="color: #800000;"> 
}
@keyframes FromLeftToRight</span>{<span style="color: #ff0000;"> 
    0% {left</span>:<span style="color: #0000ff;">0</span>;}<span style="color: #800000;">
    100% </span>{<span style="color: #ff0000;">left</span>:<span style="color: #0000ff;">800px</span>;}<span style="color: #800000;"> 
}</span>

　2) 애니메이션 이름（애니메이션 이름)

요소에 적용된 애니메이션 이름은 @keyframes 규칙과 함께 사용해야 합니다. 애니메이션 이름은 @keyframes로 정의되기 때문입니다.

　애니메이션 이름: 없음 <식별자>

　: 하나 이상의 애니메이션 이름을 정의합니다. 애니메이션 이름이 여러 개인 경우 쉼표로 구분합니다.

예: 

<span style="color: #800000;">div</span>{<span style="color: #ff0000;">
    -webkit-animation-name</span>:<span style="color: #0000ff;">FromLeftToRight</span>;<span style="color: #ff0000;">
    -moz-animation-name</span>:<span style="color: #0000ff;">FromLeftToRight</span>;<span style="color: #ff0000;">
    -o-animation-name</span>:<span style="color: #0000ff;">FromLeftToRight</span>;<span style="color: #ff0000;">
    animation-name</span>:<span style="color: #0000ff;">FromLeftToRight</span>;
}<span style="color: #800000;">
@-webkit-keyframes FromLeftToRight</span>{<span style="color: #ff0000;">
    0% {left</span>:<span style="color: #0000ff;">0</span>;}<span style="color: #800000;">
    100% </span>{<span style="color: #ff0000;">left</span>:<span style="color: #0000ff;">800px</span>;}<span style="color: #800000;"> 
}
@-moz-keyframes FromLeftToRight</span>{<span style="color: #ff0000;">
    0% {left</span>:<span style="color: #0000ff;">0</span>;}<span style="color: #800000;">
    100% </span>{<span style="color: #ff0000;">left</span>:<span style="color: #0000ff;">800px</span>;}<span style="color: #800000;">

효과:

F5를 눌러 애니메이션을 새로고침하세요. (직사각형이 3초 안에 오른쪽으로 500px 이동합니다.)

 

 　　4）动画的过渡速度（animation-timing-function）

　　　　animation-timing-function : ease | linear | ease-in | ease-out | ease-in-out | cubic-bezier(n,n,n,n)

　　　　①ease : 默认值，逐渐变慢(等于 cubic-bezier(0.25,0.1,0.25,1))

　　　　②linear : 匀速过渡效果(等于 cubic-bezier(0,0,1,1))

　　　　③ease-in : 加速的过渡效果(等于 cubic-bezier(0.42,0,1,1))

　　　　④ease-out : 减速的过渡效果(等于 cubic-bezier(0,0,0.58,1))

　　　　⑤ease-in-out : 加速然后减速(等于cubic-bezier (0.42, 0, 0.58, 1))

　　　　⑥cubic-bezier(n,n,n,n)：在 cubic-bezier 函数中定义自己的值，可能的值是 0 至 1 之间的数值。
