animation-duration

« CSS « CSS Reference

Summary

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.

• Initial value 0s
• Applies to all elements, and ::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

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.
