transition-duration

{{CSSRef}}

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.

{{EmbedInteractiveExample("pages/css/transition-duration.html")}}

You may specify multiple durations; each duration will be applied to the corresponding property as specified by the {{ cssxref("transition-property") }} property, which acts as a master list. If the number of specified durations is less than in the master list, the user agent repeats the list of durations. If the number of specified durations is more than in the master list, the list is truncated to the right size. In both the cases, 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: revert;
transition-duration: revert-layer;
transition-duration: unset;

Values

<time>
- : Is a {{cssxref("<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.

Example showing different durations

HTML

<div class="box duration-1">0.5 seconds</div>

<div class="box duration-2">2 seconds</div>

<button id="change">Change</button>

CSS

.box {
