_Just-add-water CSS animation_

`animate.css` is a bunch of cool, fun, and cross-browser animations for you to use in your projects. Great for emphasis, home pages, sliders, and general just-add-water-awesomeness.

## Installation

Install via npm:

```bash
$ npm install animate.css --save
```

or yarn:

```bash
$ yarn add animate.css
```

## Usage

To use animate.css in your website, simply drop the stylesheet into your document's `<head>`, and add the class `animated` to an element, along with any of the animation names. That's it! You've got a CSS animated element. Super!

```html
<head>
  <link rel="stylesheet" href="animate.min.css">
</head>
```

or use a CDN hosted version by [CDNJS](https://cdnjs.com/libraries/animate.css)

```html
<head>
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.7.0/animate.min.css">
</head>
```

### Animations

To animate an element, add the class `animated` to an element. You can include the class `infinite` for an infinite loop. Finally you need to add one of the following classes to the element:

| Class Name        |                    |                     |                      |
| ----------------- | ------------------ | ------------------- | -------------------- |
| `bounce`          | `flash`            | `pulse`             | `rubberBand`         |
| `shake`           | `headShake`        | `swing`             | `tada`               |
| `wobble`          | `jello`            | `bounceIn`          | `bounceInDown`       |
| `bounceInLeft`    | `bounceInRight`    | `bounceInUp`        | `bounceOut`          |
| `bounceOutDown`   | `bounceOutLeft`    | `bounceOutRight`    | `bounceOutUp`        |
| `fadeIn`          | `fadeInDown`       | `fadeInDownBig`     | `fadeInLeft`         |
| `fadeInLeftBig`   | `fadeInRight`      | `fadeInRightBig`    | `fadeInUp`           |
| `fadeInUpBig`     | `fadeOut`          | `fadeOutDown`       | `fadeOutDownBig`     |
| `fadeOutLeft`     | `fadeOutLeftBig`   | `fadeOutRight`      | `fadeOutRightBig`    |
| `fadeOutUp`       | `fadeOutUpBig`     | `flipInX`           | `flipInY`            |
| `flipOutX`        | `flipOutY`         | `lightSpeedIn`      | `lightSpeedOut`      |
| `rotateIn`        | `rotateInDownLeft` | `rotateInDownRight` | `rotateInUpLeft`     |
| `rotateInUpRight` | `rotateOut`        | `rotateOutDownLeft` | `rotateOutDownRight` |
| `rotateOutUpLeft` | `rotateOutUpRight` | `hinge`             | `jackInTheBox`       |
| `rollIn`          | `rollOut`          | `zoomIn`            | `zoomInDown`         |
| `zoomInLeft`      | `zoomInRight`      | `zoomInUp`          | `zoomOut`            |
| `zoomOutDown`     | `zoomOutLeft`      | `zoomOutRight`      | `zoomOutUp`          |
| `slideInDown`     | `slideInLeft`      | `slideInRight`      | `slideInUp`          |
| `slideOutDown`    | `slideOutLeft`     | `slideOutRight`     | `slideOutUp`         |
| `heartBeat`       |

Full example:

```html
<h1 class="animated infinite bounce delay-2s">Example</h1>
```

[Check out all the animations here!](https://daneden.github.io/animate.css/)

It's possible to change the duration of your animations, add a delay or change the number of times that it plays:

```css
.yourElement {
  animation-duration: 3s;
  animation-delay: 2s;
  animation-iteration-count: infinite;
}
```

## Usage with Javascript

You can do a whole bunch of other stuff with animate.css when you combine it with Javascript. A simple example:

```javascript
const element =  document.querySelector('.my-element')
element.classList.add('animated', 'bounceOutLeft')
```

You can also detect when an animation ends:

```javascript
const element =  document.querySelector('.my-element')
element.classList.add('animated', 'bounceOutLeft')

element.addEventListener('animationend', function() { doSomething() })
```

You can use this simple function to add and remove the animations:

```javascript
function animateCSS(element, animationName, callback) {
    const node = document.querySelector(element)
    node.classList.add('animated', animationName)

function handleAnimationEnd() {
        node.classList.remove('animated', animationName)
        node.removeEventListener('animationend', handleAnimationEnd)

if (typeof callback === 'function') callback()
    }

node.addEventListener('animationend', handleAnimationEnd)
}
```

And use it like this:

```javascript
animateCSS('.my-element', 'bounce')

// or
animateCSS('.my-element', 'bounce', function() {
  // Do something after animation
})
```

Notice that the examples are using ES6's `const` declaration, dropping support for IE10 and some aging browsers. If you prefer, switch the `const` to `var` declarations and IE10 and some old browsers will get support (they still have to provide [classList](https://developer.mozilla.org/en-US/docs/Web/API/Element/classList) support, so do your [research](https://caniuse.com/#feat=classlist)).

## Setting _Delay_ and _Speed_

### Delay Class

It's possible to add delays directly on the element's class attribute, just like this:

```html
<div class="animated bounce delay-2s">Example</div>
```

| Class Name | Delay Time |
| ---------- | ---------- |
| `delay-2s` | `2s`       |
| `delay-3s` | `3s`       |
| `delay-4s` | `4s`       |
| `delay-5s` | `5s`       |

> _**Note**: The default delays are from 1 second to 5 seconds only. If you need custom delays, add it directly to your own CSS code._

### Slow, Slower, Fast, and Faster Class

It's possible to control the speed of the animation by adding these classes, as a sample below:

```html
<div class="animated bounce faster">Example</div>
```

| Class Name | Speed Time |
| ---------- | ---------- |
| `slow`     | `2s`       |
| `slower`   | `3s`       |
| `fast`     | `800ms`    |
| `faster`   | `500ms`    |

> _**Note**: The `animated` class has a default speed of `1s`. If you need custom duration, add it directly to your own CSS code._

## Custom Builds

Animate.css is powered by [gulp.js](http://gulpjs.com/), which means you can create custom builds pretty easily. First of all, you’ll need Gulp and all other dependencies:

```sh
$ cd path/to/animate.css/
$ sudo npm install
```

Next, run `gulp` to compile your custom builds. For example, if you want only some of the “attention seekers”, simply edit the `animate-config.json` file to select only the animations you want to use.

```javascript
"attention_seekers": {
  "bounce": true,
  "flash": false,
  "pulse": false,
  "shake": true,
  "headShake": true,
  "swing": true,
  "tada": true,
  "wobble": true,
  "jello":true
}
```

## Accessibility

Animate.css supports the [`prefers-reduced-motion` media query](https://webkit.org/blog/7551/responsive-design-for-motion/) so that users with motion sensitivity can opt out of animations. On supported platforms (currently Firefox, OSX Safari and iOS Safari), users can select "reduce motion" on their operating system preferences and it will turn off CSS transitions for them without any further work required.
