This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
animation-direction CSS 속성은 애니메이션이 앞으로, 뒤로 또는 앞뒤로 번갈아 재생되어야하는지 여부를 지정합니다.
/* Single animation */ animation-direction: normal; animation-direction: reverse; animation-direction: alternate; animation-direction: alternate-reverse; /* Multiple animations */ animation-direction: normal, reverse; animation-direction: alternate, reverse, normal; /* Global values */ animation-direction: inherit; animation-direction: initial; animation-direction: unset;
It is often convenient to use the shorthand property animation to set all animation properties at once.
| 초기값 | normal |
|---|---|
| 적용대상 | all elements, ::before and ::after pseudo-elements |
| 상속 | no |
| Media | visual |
| Computed value | as specified |
| Animation type | discrete |
| Canonical order | the unique non-ambiguous order defined by the formal grammar |
Syntax
Values
normal- The animation plays forwards each cycle. In other words, each time the animation cycles, the animation will reset to the beginning state and start over again. This is the default value.
reverse- The animation plays backwards each cycle. In other words, each time the animation cycles, the animation will reset to the end state and start over again. Animation steps are performed backwards, and timing functions are also reversed. For example, an
ease-intiming function becomesease-out. alternate- The animation reverses direction each cycle, with the first iteration being played forwards. The count to determine if a cycle is even or odd starts at one.
alternate-reverse- The animation reverses direction each cycle, with the first iteration being played backwards. The count to determinate if a cycle is even or odd starts at one.
Note: When you specify multiple comma-separated values on an animation-* property, they will be assigned to the animations specified in the animation-name property in different ways depending on how many there are. For more information, see Setting multiple animation property values.
Formal syntax
<single-animation-direction>#where
<single-animation-direction> = normal | reverse | alternate | alternate-reverse

[1] In addition to the unprefixed support, Gecko 44.0 (Firefox 44.0 / Thunderbird 44.0 / SeaMonkey 2.41) added support for a -webkit- prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.
