animation-duration property CSS Reference

Definition and Usage

The animation-duration CSS property specifies the length of time that an animation should take to complete one cycle.

A value of 0s, which is the default value, indicates that no animation should occur.

It is often convenient to use the shorthand property animation to set all animation properties at once.

Syntax

Formal syntax: <time>#

animation-duration: 6s
animation-duration: 120ms
animation-duration: 1s, 15s
animation-duration: 10s, 30s, 230ms

Values

<time>: The duration that an animation should take to complete one cycle. This may be specified in either seconds (by specifying s as the unit) or milliseconds (by specifying ms as the unit). If you don't specify a unit, the declaration will be invalid.

Note: Negative values are invalid, causing the declaration to be ignored. Note that some early, prefixed, implementations may consider them as identical to 0s.
