# 引入動畫效果 - AOS

[AOS Github Repo](https://github.com/michalsnik/aos)
[AOS Demo 頁面](https://michalsnik.github.io/aos/)

## 引入方法
### 1. CDN 引入
在 head 加上樣式：

<link rel="stylesheet" href="https://unpkg.com/aos@next/dist/aos.css" />

在 body 結尾標籤加上 script：

<script src="https://unpkg.com/aos@next/dist/aos.js"></script>
<script>
	AOS.init();
</script>

### 2. 安裝 package

#### 下指令
1. `yarn add aos@next`
或
2. `npm install --save aos@next`

#### 引入 script styles 並初始化 AOS：

import AOS from 'aos';
import 'aos/dist/aos.css'; // You can also use <link> for styles
// ..
AOS.init();

## 額外設定

// 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

});

## 使用方法
