Utility classes

Animate.css comes packed with a few utility classes to simplify its use.

Delay classes

You can add delays directly on the element's class attribute, just like this:

<div class="animate__animated animate__bounce animate__delay-2s">Example</div>

Animate.css provides the following delays:

Class name	Default delay time
animate__delay-2s	2s
animate__delay-3s	3s
animate__delay-4s	4s
animate__delay-5s	5s

The provided delays are from 1 to 5 seconds. You can customize them setting the --animate-delay property to a longer or a shorter duration:

/* All delay classes will take 2x longer to start */
:root {
  --animate-delay: 2s;
}

/* All delay classes will take half the time to start */
:root {
  --animate-delay: 0.5s;
}

Slow, slower, fast, and Faster classes

You can control the speed of the animation by adding these classes, as below:

<div class="animate__animated animate__bounce animate__faster">Example</div>

Class name	Default speed time
animate__slow	2s
animate__slower	3s
animate__fast	800ms
animate__faster	500ms

The animate__animated class has a default speed of 1s. You can also customize the animations duration through the --animate-duration property, globaly or locally. This will affect both the animations and the utility classes. Example:

/* All animations will take twice as long to finish */
:root {
  --animate-duration: 2s;
}

/* Only this element will take half the time to finish */
.my-element {
  --animate-duration: 0.5s;
}

Notice that some animations have a duration of less than 1 second. As we used the CSS calc() function, setting the duration through the --animation-duration property will respect these ratios. So, when you change the global duration all the animations will respond to that change!

Repeating classes

You can control the iteration count of the animation by adding these classes, like below:

<div class="animate__animated animate__bounce animate__repeat-2">Example</div>

Class Name	Default iteration count
animate__repeat-1	1
animate__repeat-2	2
animate__repeat-3	3

As with the repeat and speed classes, the animate__repeat class is based on the --animate-repeat property and has a default iteration count of 1. You can customize them setting the --animate-repeat property to a longer or a shorter value:

/* The element will repeat the animation 2x
   It's better to set this property only locally and not globally or
   you might end up with a messy situation */
.my-element {
  --animate-repeat: 2;
}
