The transition CSS property is a shorthand property for transition-property, transition-duration, transition-timing-function, and transition-delay.

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.

Syntax

/* Apply to 1 property */
/* property name | duration */
transition: margin-right 4s;

/* property name | duration | delay */
transition: margin-right 4s 1s;

/* property name | duration | timing function */
transition: margin-right 4s ease-in-out;

/* property name | duration | timing 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: 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.
  • zero or one <single-transition-timing-function> value representing the timing function to use
  • zero, one, or two <time> values. The first value that can be parsed as a time is assigned to the transition-duration, and the second value that can be parsed as a time is assigned to transition-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.

Formal syntax

<single-transition>#

where
<single-transition> = [ none | <single-transition-property> ] || <time> || <single-transition-timing-function> || <time>

where
<single-transition-property> = all | <custom-ident>
<single-transition-timing-function> = <single-timing-function>

where
<single-timing-function> = linear | <cubic-bezier-timing-function> | <step-timing-function> | <frames-timing-function>

where
<cubic-bezier-timing-function> = ease | ease-in | ease-out | ease-in-out | cubic-bezier(<number>, <number>, <number>, <number>)
<step-timing-function> = step-start | step-end | steps(<integer>[, [ start | end ] ]?)
<frames-timing-function> = frames(<integer>)

Examples

There are several more examples of CSS transitions included in the Using CSS transitions article.

Notes
Notes Before Firefox 57, transitions do not work when transitioning from a text-shadow with a color specified to a text-shadow without a color specified (see bug 726550).
Notes Before Firefox 57, cancelling a filling animation (for example, with animation-fill-mode: forwards set) can trigger a transition set on the same element, although only once (see bug 1192592 and these test cases for more information).
Notes Before Firefox 57, the background-position property can't be transitioned between two values containing different numbers of <position> values, for example background-position: 10px 10px; and background-position: 20px 20px, 30px 30px; (see bug 1390446).
