### 載入步驟

在 </body>前加上以下程式碼

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

AOS 單一設計

<div
    data-aos="fade-up"
    data-aos-offset="200"
    data-aos-delay="50"
    data-aos-duration="1000"
    data-aos-easing="ease-in-out"
    data-aos-mirror="true"
    data-aos-once="false"
    data-aos-anchor-placement="top-center">
  </div>

AOS 全域設計

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
