Usage Guide for OnScrollReveal Component

Import the OnScrollReveal component on the desired page.
Add the scroll-animation class to any HTML elements you want to animate on scroll.
Add the animation class name: scroll-animation-default or swing-in-left to specify the animation you want to use.
Use delay classes (Optional), such as delay-300, to stagger the animation start time for sequential animations.

---
import OnScrollReveal from 'astro-onscroll-animations';
---

<body>
  <div class="hero">
        <h1 class="scroll-animation scroll-animation-default">Hello</h1>
        <h1 class="scroll-animation scroll-animation-default delay-300">World!</h1>
  </div>
  <div class="hero">
        <h2 class="scroll-animation swing-in-left delay-600">Text</h2>
        <h2 class="scroll-animation swing-in-left delay-750 ">Another Text</h2>
  </div>

  <!-- Initialize the OnScrollReveal functionality -->
  <OnScrollReveal />
</body>

Key Points:

scroll-animation: Attach this class to elements that should animate when they enter the viewport.

Animation Classes: there are two animation classes available: scroll-animation-default and swing-in-left scroll-animation-default

.scroll-animation-default {
  transform: translateY(50px);
  opacity: 0;
  transition: all 0.5s ease-in;
}

.scroll-animated-default {
  transform: translateY(0);
  opacity: 1;
}

swing-in-left

.swing-in-left {
  animation: none;
}

.swing-in-left-anim {
  animation-name: swingAnim;
  animation-duration: 2s;
  animation-timing-function: ease;
  animation-fill-mode: forwards;
  animation-iteration-count: 1;
  opacity: 1;
}

@keyframes swingAnim {
  0% {
    opacity: 0;
    transform: rotateY(100deg);
    transform-origin: left;
  }

  100% {
    opacity: 1;
    transform: rotateY(0);
    transform-origin: left;
  }
}

Delay Classes: To create a sequence of animations, you can add delay classes like delay-300, delay-600, etc. The value represents the delay in milliseconds before the animation starts. Delay classes starts from delay-300 which indicated to delay 300ms to delay-1200, and available in 150ms intervals:
- delay-300 – 300ms delay
- delay-450 – 450ms delay
- delay-600 – 600ms delay
- delay-750 – 750ms delay
- delay-900 – 900ms delay
- delay-1050 – 1050ms delay
- delay-1200 – 1200ms delay

Example:

In this example, the first heading (Hello) animates immediately when it appears, while the second heading (World!) starts its animation 300ms later. (Text) and (Another Text) animates with the style of swing-in-left animation with corresponding delays.

This structured approach should make it easier to follow the guide and implement the OnScrollReveal component effectively.
