SenangWebs Animations (SWA) is a lightweight JavaScript library that enables smooth, customizable animations for HTML elements as they enter the viewport during scrolling. With minimal setup, you can add engaging animations to your web pages, enhancing the user experience.

• Easy to integrate with existing projects
• Supports various animation types: fade, flip, zoom, slide, and bounce
• Customizable animation parameters via data attributes
• Group animations with simultaneous or sequential timing
• Efficient performance using Intersection Observer API
• Global configuration options
• Responsive and works on all modern browsers

https://unpkg.com/senangwebs-animations@latest/examples/index.html

npm install senangwebs-animations

You can include SenangWebs Animations directly in your HTML file using unpkg:

<link rel="stylesheet" href="https://unpkg.com/senangwebs-animations@latest/dist/swa.css">
<script src="https://unpkg.com/senangwebs-animations@latest/dist/swa.js"></script>

1. Include the SWA CSS and JavaScript files in your HTML:

<!-- If installed via npm -->
<link rel="stylesheet" href="path/to/swa.css">
<script src="path/to/swa.js"></script>

<!-- Or if using unpkg -->
<link rel="stylesheet" href="https://unpkg.com/senangwebs-animations@latest/dist/swa.css">
<script src="https://unpkg.com/senangwebs-animations@latest/dist/swa.js"></script>

2. Initialize the library in your JavaScript code:

document.addEventListener('DOMContentLoaded', function() {
  SWA.init({
    // Optional global configuration
    offset: 120,
    duration: 600,
    easing: 'ease-out',
    once: true,
  });
});

3. Add data attributes to the HTML elements you want to animate:

<div
  data-swa="fade-up"
  data-swa-offset="200"
  data-swa-delay="50"
  data-swa-duration="1000"
  data-swa-easing="ease-in-out"
  data-swa-mirror="true"
  data-swa-once="false"
  data-swa-anchor-placement="top-center"
>
  This element will animate when scrolled into view.
</div>

4. For group animations, use the data-swa-group attribute:

<div 
  data-swa-group="fade-up"
  data-swa-group-type="sequence"
  data-swa-group-interval-duration="500"
  data-swa-group-offset="200"
  data-swa-group-delay="100"
  data-swa-group-duration="1000"
  data-swa-group-easing="ease-in-out"
  data-swa-group-mirror="true"
  data-swa-group-once="false"
>
  <div>Child 1</div>
  <div>Child 2</div>
  <div>Child 3</div>
</div>

You can configure animations for individual elements using the following attributes:

• data-swa: Animation type (e.g., "fade-up", "flip-left", "zoom-in", "slide-right", "bounce-in")
• data-swa-offset: Distance (in pixels) from the viewport before triggering the animation
• data-swa-delay: Delay before starting the animation (in milliseconds)
• data-swa-duration: Duration of the animation (in milliseconds)
• data-swa-easing: Easing function for the animation (e.g., "ease-in-out", "linear")
• data-swa-mirror: When set to "true", the animation repeats when scrolling back up
• data-swa-once: If "true", the animation only occurs once
• data-swa-anchor-placement: The anchor point of the element for animation start (e.g., "top-center", "center-bottom")

Group animations use similar options, but with a group prefix:

• data-swa-group: Animation type for all children (overridden by individual data-swa on children)
• data-swa-group-type: "simultaneous" (default) or "sequence"
• data-swa-group-interval-duration: Time interval between animations for "sequence" type (in milliseconds)
• data-swa-group-offset: Offset for the entire group
• data-swa-group-delay: Delay before starting the group animation
• data-swa-group-duration: Duration for each animation in the group
• data-swa-group-easing: Easing function for the group animations
• data-swa-group-mirror: Mirror setting for the group
• data-swa-group-once: Once setting for the group
• data-swa-group-anchor-placement: Anchor placement for the group

• Fade: fade, fade-up, fade-down, fade-left, fade-right, fade-up-left, fade-up-right, fade-down-left, fade-down-right
• Flip: flip-up, flip-down, flip-left, flip-right
• Zoom: zoom-in, zoom-out
• Slide: slide-up, slide-down, slide-left, slide-right, slide-up-left, slide-up-right, slide-down-left, slide-down-right
• Bounce: bounce-in, bounce-out

SenangWebs Animations works on all modern browsers that support the Intersection Observer API, including:

• Chrome 51+
• Firefox 55+
• Safari 12.1+
• Edge 15+
• Opera 38+

For older browsers, consider using a polyfill for the Intersection Observer API.
