CSS transition-duration Property

Description

The transition-duration property sets the time, in seconds or milliseconds, how long the transition animation should last before it is completed. By default, the value is 0s, which means that there is no animation, the transition occurs instantly.

Initial value: 0s
Applies to: All elements, :before and :after pseudo elements
Inherited: No
Media: Interactive
Computed value: Same as specified value
Animatable: No
CSS Version: CSS3
JavaScript syntax: object.style.transitionDuration

Syntax

transition-duration: <time> [, <time>]*

Values

<time>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

HTML

<div class="test" > 5s </div> 

<div class="test2" > 2s </div> 

<div class="test3"> 400ms </div>

CSS

div {
   width: 70px;
   height: 70px; 
   background-color: yellow;
   border: 5px dashed black;
   display: inline-block; 
   margin-right: 15px; 
}
div:hover {
   height: 200px; 
}
.test { 
   transition-duration: 5s;  
}
.test2 { 
   transition-duration: 2s; 
}
.test3 { 
   transition-duration: 400ms;  
}
