Custom Reveal Animations on Scroll – DOM Flowt

DOM Flowt is a lightweight JavaScript AOS (animate on scroll) library that transforms static elements into smoothly animated components as they enter the viewport.

It’s worth a look if you need simple “reveal” effects without pulling in a heavy animation engine or writing Intersection Observer boilerplate.

How

to use it:

1. Download the package and link the dom-flowt.js and dom-flowt.css files in your HTML.

<link rel="stylesheet" href="/css/dom-flowt.css" media="screen"/>
<script src="/lib/stable/dom-flowt.js"></script>

2. Attach the DomFlowt.watch() method to a scroll event listener. Typically, you’ll attach this to the window object.

window.addEventListener("scroll", function() {
  DomFlowt.watch();
});
// Initial check in case elements are already in view on load
document.addEventListener('DOMContentLoaded', function() {
  DomFlowt.watch();
});

3. Attach scroll-triggered animations to elements using the following HTML data attributes:

• dom-flowt-is-visible="false": Required. This attribute flags the element for processing and sets its initial state as “not visible”. The library changes this value (likely internally or via another attribute/class) once the animation triggers. It must be set to false
• dom-flowt-type="{animation-type}": Specifies the animation effect: “pop-up”, “float-left”, “flip-vertical”. Default: “fade”.
• dom-flowt-duration="{time-in-ms}": Sets the animation duration in milliseconds. Default: “500”.
• dom-flowt-delay="{time-in-ms}": Sets a delay before the animation starts, in milliseconds. Default: “0”
• dom-flowt-repeat="{repeat|no-repeat}": Controls if the animation runs again if the element scrolls out of view and then back in. Default: “repeat”

<nav 
  class="nav" 
  dom-flowt-is-visible="false" 
  dom-flowt-type="fade" 
  dom-flowt-duration="1000"
  dom-flowt-delay="100"
  dom-flowt-repeat="no-repeat">
  ...
</nav>
