A propriedade de CSS  transition é uma propriedade abreviada para transition-property, transition-duration, transition-timing-function e transition-delay. Ela permite definir a transição entre dois estados de um elemento. Estados diferentes podem ser definidos usando pseudo-classes tais como :hover ou :active; ou dinamicamente, usando javascript.

Canonical orderorder of appearance in the formal grammar of the values


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

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

/* property name | duration | timing function | delay */
transition: margin-left 4s ease-in-out 1s;

/* Apply to 2 properties */
transition: margin-left 4s, color 1s;

/* Apply to all changed properties */
transition: all 0.5s ease-out;

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

Note that order is important within the items in this property: 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> = [ none | <single-transition-property> ] || <time> || <single-transition-timing-function> || <time>

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

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

<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>)


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