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 begining, or immediately and partway through the animation cycle.

/* Single animation */
animation-delay: 3s;
animation-delay: 0s;
animation-delay: -1500ms;
/* Multiple animations */
animation-delay: 2.1s, 480ms;

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

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] In addition to the unprefixed support, Gecko 44.0 (Firefox 44.0 / Thunderbird 44.0 / SeaMonkey 2.41) added support for a -webkit- prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.
