The transition-property CSS property is used to specify the names of CSS properties to which a transition effect should be applied.

Note: The set of properties that can be animated is subject to change. As such, you should avoid including any properties in the list that don't currently animate, as someday they might, causing unexpected results.

If you specify a shorthand property (for example, background) all of its longhand sub-properties that can be animated will be.

No properties will transition.
All properties that can have an animated transition will do so.
A string identifying the property to which a transition effect should be applied when its value changes. This identifier is composed by case-insensitive letters a to z, numbers 0 to 9, an underscore (_) or a dash(-). The first non-dash character must be a letter (that is: no number at the beginning of it, even preceded by a dash). Also, two dashes are forbidden at the beginning of the identifier.

Formal syntax

none | <single-transition-property>#

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


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