# Contributing to AOS
## Bugs
Found a bug? Have a problem with AOS? Please check past issues, maybe someone already had that problem. If you don't find similar issue create new, but remember to add accurate informations so that I can dig into it straight away. If it's possible add CodePen example that presents called issue.
## Development process
### Setup
- Install all dependencies:
```
yarn
```
- Run rollup and dev server in watch mode:
```
yarn dev
```
This will run [local-server](http://localhost:8080), build AOS and automatically refresh page on any changes (it loads content from `demo` folder).
### Testing
Before you create Pull Request make sure all tests are passing.
In order to do so run:
```
yarn test
```
If you want to run tests while working on the plugin (when local-server is running on), run:
```
yarn test:dev
```
### Commiting changes
If all tests are passing then you're good to go. Commit your changes, but remember to **not commit `dist` folder**.
Create well described Pull Request with as many informations as possible and wait for my answer :) I'd be happy to make a code review and put some thougths.

### 🚀 [Demo](http://michalsnik.github.io/aos/)
### 🌟 Codepen Examples
- [Different built-in animations](http://codepen.io/michalsnik/pen/WxNdvq)
- [With anchor setting in use](http://codepen.io/michalsnik/pen/jrOYVO)
- [With anchor-placement and different easings](http://codepen.io/michalsnik/pen/EyxoNm)
- [With simple custom animations](http://codepen.io/michalsnik/pen/WxvNvE)
👉 To get a better understanding how this actually works, I encourage you to check [my post on CSS-tricks](https://css-tricks.com/aos-css-driven-scroll-animation-library/).
---
## ⚙ Installation
### Basic
Add styles in `
`:
```html
```
Add script right before closing `` tag, and initialize AOS:
```html
```
### Using package managers
Install `aos` package:
* `yarn add aos@next`
* or `npm install --save aos@next`
Import script, styles and initialize AOS:
```js
import AOS from 'aos';
import 'aos/dist/aos.css'; // You can also use for styles
// ..
AOS.init();
```
In order to make it work you'll have to make sure your build process has configured styles loader, and bundles it all correctly.
If you're using [Parcel](https://parceljs.org/) however, it will work out of the box as provided.
---
## 🤔 How to use it?
### 1. Initialize AOS:
```js
AOS.init();
// You can also pass an optional settings object
// below listed default settings
AOS.init({
// Global settings:
disable: false, // accepts following values: 'phone', 'tablet', 'mobile', boolean, expression or function
startEvent: 'DOMContentLoaded', // name of the event dispatched on the document, that AOS should initialize on
initClassName: 'aos-init', // class applied after initialization
animatedClassName: 'aos-animate', // class applied on animation
useClassNames: false, // if true, will add content of `data-aos` as classes on scroll
disableMutationObserver: false, // disables automatic mutations' detections (advanced)
debounceDelay: 50, // the delay on debounce used while resizing window (advanced)
throttleDelay: 99, // the delay on throttle used while scrolling the page (advanced)
// Settings that can be overridden on per-element basis, by `data-aos-*` attributes:
offset: 120, // offset (in px) from the original trigger point
delay: 0, // values from 0 to 3000, with step 50ms
duration: 400, // values from 0 to 3000, with step 50ms
easing: 'ease', // default easing for AOS animations
once: false, // whether animation should happen only once - while scrolling down
mirror: false, // whether elements should animate out while scrolling past them
anchorPlacement: 'top-bottom', // defines which position of the element regarding to window should trigger the animation
});
```
### 2. Set animation using `data-aos` attribute:
```html
```
And adjust behaviour by using `data-aos-*` attributes:
```html
```
[See full list of all animations, easings and anchor placements](https://github.com/michalsnik/aos#animations)
#### Anchor
There is also a setting that can be used only on per-element basis:
* `data-aos-anchor` - element whose offset will be used to trigger animation instead of an actual one.
Examples:
```html
```
This way you can trigger animation on one element, while you scroll to another - useful in animating fixed elements.
---
## API
AOS object is exposed as a global variable, for now there are three methods available:
* `init` - initialize AOS
* `refresh` - recalculate all offsets and positions of elements (called on window resize)
* `refreshHard` - reinit array with AOS elements and trigger `refresh` (called on DOM changes that are related to `aos` elements)
Example execution:
```javascript
AOS.refresh();
```
By default AOS is watching for DOM changes and if there are any new elements loaded asynchronously or when something is removed from DOM it calls `refreshHard` automatically. In browsers that don't support `MutationObserver` like IE you might need to call `AOS.refreshHard()` by yourself.
`refresh` method is called on window resize and so on, as it doesn't require to build new store with AOS elements and should be as light as possible.
---
## JS Events
AOS dispatches two events on document: `aos:in` and `aos:out` whenever any element animates in or out, so that you can do extra stuff in JS:
```js
document.addEventListener('aos:in', ({ detail }) => {
console.log('animated in', detail);
});
document.addEventListener('aos:out', ({ detail }) => {
console.log('animated out', detail);
});
```
You can also tell AOS to trigger custom event on specific element, by setting `data-aos-id` attribute:
```html
```
Then you'll be able to listen for two custom events then:
- `aos:in:super-duper`
- `aos:out:super-duper`
---
## Recipes:
#### Adding custom animations:
Sometimes built-in animations are just not enough. Let's say you need one box to have different animation depending on resolution.
Here's how you could do it:
```css
[data-aos="new-animation"] {
opacity: 0;
transition-property: transform, opacity;
&.aos-animate {
opacity: 1;
}
@media screen and (min-width: 768px) {
transform: translateX(100px);
&.aos-animate {
transform: translateX(0);
}
}
}
```
Then use it in HTML:
```html
```
The element will only animate opacity on mobile devices, but from 768px width it'll also slide from right to left.
#### Adding custom easing:
Similar to animations you can add custom easings:
```css
[data-aos] {
body[data-aos-easing="new-easing"] &,
&[data-aos][data-aos-easing="new-easing"] {
transition-timing-function: cubic-bezier(.250, .250, .750, .750);
}
}
```
#### Customizing default animations distance
Default distance for built-in animations is 100px. As long as you're using SCSS though, you can override it:
```css
$aos-distance: 200px; // It has to be above import
@import 'node_modules/aos/src/sass/aos.scss';
```
You have to however configure your build process to allow it to import styles from `node_modules` beforehand.
#### Integrating external CSS animation library (e.g. Animate.css):
Use `animatedClassName` to change default behaviour of AOS, to apply class names placed inside `data-aos` on scroll.
```html
```
```js
AOS.init({
useClassNames: true,
initClassName: false,
animatedClassName: 'animated',
});
```
The above element will get two classes: `animated` and `fadeInUp`. Using different combinations of the three above settings, you should be able to integrate any external CSS animation library.
External libraries however don't care too much about animation state before the actual animation. So if you want those elements to be not visible before scrolling, you might need to add similar styles:
```css
[data-aos] {
visibility: hidden;
}
[data-aos].animated {
visibility: visible;
}
```
---
## Caveats:
#### setting: `duration`, `delay`
Duration and delay accept values from 50 to 3000, with step 50ms, it's because those are handled by css, and to not make css longer than it is already I implemented only a subset. I believe those should cover most cases.
If not, you can write simple CSS that will add another duration, for example:
```css
body[data-aos-duration='4000'] [data-aos],
[data-aos][data-aos][data-aos-duration='4000'] {
transition-duration: 4000ms;
}
```
This code will add 4000ms duration available for you to set on AOS elements, or to set as global duration while initializing AOS script.
Notice that double `[data-aos][data-aos]` - it's not a mistake, it is a trick, to make individual settings more important than global, without need to write ugly "!important" there :)
Example usage:
```html
```
