CSS animation-duration Property
The animation-duration property defines the length of time (in seconds or milliseconds) that animation takes to complete its one cycle. Very often the animation shorthand property is used to set all animation properties at once. The default value for the animation-duration property is 0, which means that the animation starts immediately and the keyframes don’t have an effect. Negative values are invalid and they cause the property to be ignored. But they may be considered as equal to 0s by some earlier implementations.
When multiple comma-separated values are specified for any animation property, they will be attached to the animations that are defined in animation-name differently.
The animation-duration property is one of the CSS3 properties.
