Add this code to the <head>

<!-- Link Scroller CSS -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/AdirDiz/scroller@main/scroller.min.css" />

Add this code to </body>

<!-- Scroller JS -->
<script src="https://cdn.jsdelivr.net/gh/AdirDiz/scroller@main/scroller.min.js"></script>

Use this structure to make it work

<div class="scroller"> <!--  It's a unique class under each setting for scroller.js-->
 <div class="scroller-wrapper"> <!-- This class always remains the same!!!-->
 
 <!-- Next, we place all the elements that need to participate in the infinite carousel.-->
  <div class="scroller-item"> Content </div>
  <img src="Link to your image">
  
 </div>
</div>

Or we can use this structure in Webflow

Set the settings and make it work for you.

  <!-- Initialize Scroller -->
<script>
  initMyScroller(".scroller", { 
  	speed: 20, // Animation speed in seconds. If no parameter is set default is 40 seconds.
    	direction: "left", // Direction of travel. "left" or "right". If the parameter is not set, the movement will be to the left  
    	columnGap: 2, // Distance between elements in REM
    	duplicates: 1 //Number of duplicates. If there are not enough elements for scrolling, I recommend to set 2 or more. The default is 1 duplicate. 
  }); 
</script>
