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.
Summary
The animation-iteration-count
CSS property defines the number of times an animation cycle should be played before stopping.
It is often convenient to use the shorthand property animation
to set all animation properties at once.
Initial value | 1 |
---|---|
Applies to | all elements, ::before and ::after pseudo-elements |
Inherited | no |
Media | visual |
Computed value | as specified |
Animatable | no |
Canonical order | the unique non-ambiguous order defined by the formal grammar |
Syntax
animation-iteration-count: infinite; animation-iteration-count: 3; animation-iteration-count: 2.3; animation-iteration-count: 2, 0, infinite;
Values
infinite
- The animation will repeat forever.
<number>
- The number of times the animation should repeat; this is
1
by default. Negative values are invalid. You may specify non-integer values to play part of an animation cycle (for example0.5
will play half of the animation cycle).
Formal syntax
<single-animation-iteration-count>#where
<single-animation-iteration-count> = infinite | <number>
Examples
See CSS animations for examples.

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
