transition
The transition
CSS property is a shorthand property for transition-property
, transition-duration
, transition-timing-function
, and transition-delay
.
Try it
Transitions enable you to define the transition between two states of an element. Different states may be defined using pseudo-classes like :hover
or :active
or dynamically set using JavaScript.
Constituent properties
This property is a shorthand for the following CSS properties:
Syntax
css
/* Apply to 1 property */
/* property name | duration */
transition: margin-right 4s;
/* property name | duration | delay */
transition: margin-right 4s 1s;
/* property name | duration | easing function */
transition: margin-right 4s ease-in-out;
/* property name | duration | easing function | delay */
transition: margin-right 4s ease-in-out 1s;
/* Apply to 2 properties */
transition: margin-right 4s, color 1s;
/* Apply to all changed properties */
transition: all 0.5s ease-out;
/* Global values */
transition: inherit;
transition: initial;
transition: revert;
transition: revert-layer;
transition: unset;
The transition
property is specified as one or more single-property transitions, separated by commas.
Each single-property transition describes the transition that should be applied to a single property (or the special values all
and none
). It includes:
- zero or one value representing the property to which the transition should apply. This may be any one of:
- the keyword
none
- the keyword
all
- a
<custom-ident>
naming a CSS property.
- the keyword
- zero or one
<easing-function>
value representing the easing function to use - zero, one, or two
<time>
values. The first value that can be parsed as a time is assigned to thetransition-duration
, and the second value that can be parsed as a time is assigned totransition-delay
.
See how things are handled when lists of property values aren't the same length. In short, extra transition descriptions beyond the number of properties actually being animated are ignored.

Examples
Simple example
In this example, when the user hovers over the element, there is a one-second delay before the four-second font-size
transition occurs.
HTML
html
<a class="target">Hover over me</a>
CSS
We include two <time>
values. In the transition
shorthand, the first <time>
value is the transition-duration
. The second time value is the transition-delay
. Both default to 0s
if omitted.
css
.target {
font-size: 14px;
transition: font-size 4s 1s;
}
.target:hover {
font-size: 36px;
}
There are several more examples of CSS transitions included in the Using CSS transitions article.
