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-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.

|---|---|
| Applies to | all elements, ::before and ::after pseudo-elements |
| Inherited | no |
| Media | visual |

[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.
