CSS3 transition-delay Property

Topic: CSS3 Properties ReferencePrev|Next


The transition-delay CSS property defines when the transition will start (e.g. a value of 2s, indicates that the transition will begin 2 seconds after it is applied.). The value of this property can be specified in seconds (s) or milliseconds (ms).

The following table summarizes the usages context and the version history of this property.

Default value: 0s
Applies to: All elements, ::before and ::after pseudo-elements
Inherited: No
Animatable: No. See animatable properties.
Version: New in CSS3


The syntax of the property is given with:

time | initial | inherit

The example below shows the transition-delay property in action.

button {
    background: #fd7c2a;
    /* For Safari 3.0+ */
    -webkit-transition-property: background;
    -webkit-transition-duration: 4s;
    -webkit-transition-delay: 2s;
    /* Standard syntax */
    transition-property: background;
    transition-duration: 4s;
    transition-delay: 2s;
button:hover {
    background: #3cc16e;

Note: Negative values are allowed for this property. However, it will appear to have begun executing partway through its transition cycle e.g. the transition delay of -2s makes the transition start at once, but starts 2 seconds into the transition.
