The animation-delay CSS property specifies when an animation should start. You can begin the animation at a future point in time, immediately and from its beginning, or immediately and partway through the animation cycle.

It is often convenient to use the shorthand property animation to set all animation properties at once.

Syntax

/* Single animation */
animation-delay: 3s;
animation-delay: 0s;
animation-delay: -1500ms;

/* Multiple animations */
animation-delay: 2.1s, 480ms;

Values

<time>
The time offset, from the moment at which the animation is applied to the element, at which the animation should begin. This may be specified in either seconds (s) or milliseconds (ms). The unit is required.
A positive value indicates that the animation should begin after the specified amount of time has elapsed. A value of 0s, which is the default, indicates that the animation should begin as soon as it's applied.

A negative value causes the animation to begin immediately, but partway through its cycle. For example, if you specify -1s as the animation delay time, the animation will begin immediately but will start 1 second into the animation sequence. If you specify a negative value for the animation delay, but the starting value is implicit, the starting value is taken from the moment the animation is applied to the element.

Note: When you specify multiple comma-separated values on an animation-* property, they will be assigned to the animations specified in the animation-name property in different ways depending on how many there are. For more information, see Setting multiple animation property values.

1. Before Firefox 57, Firefox does not repaint elements outside the viewport that are animated into the viewport with a delay. This bug affects only some platforms, such as Windows.

2. From version 44: this feature is behind the layout.css.prefixes.webkit preference (needs to be set to true). To change preferences in Firefox, visit about:config.
