transition-duration

The transition-duration CSS property sets the length of time a transition animation should take to complete. By default, the value is 0s, meaning that no animation will occur.

You may specify multiple durations; each duration will be applied to the corresponding property as specified by the transition-property property, which acts as a master list. If there are fewer durations specified than in the master list, the user agent repeat the list of durations. If there are more durations, the list is simply truncated to the right size. In both case the CSS declaration stays valid.

Syntax

/* <time> values */
transition-duration: 6s;
transition-duration: 120ms;
transition-duration: 1s, 15s;
transition-duration: 10s, 30s, 230ms;

/* Global values */
transition-duration: inherit;
transition-duration: initial;
transition-duration: unset;

Values

<time>
Is a <time> denoting the amount of time the transition from the old value of a property to the new value should take. A time of 0s indicates that no transition will happen, that is the switch between the two states will be instantaneous. A negative value for the time renders the declaration invalid.

Formal definition

Initial value 0s
Applies to all elements, ::before and ::after pseudo-elements
Inherited no
Computed value as specified
Animation type discrete
