Multiple scroll function with jQuery

I would need a jQuery solution for a multiple scroll function. Generally, I imagine something like multiscroll.js does, but it should work with more than two columns.

This is how the basic layout could look like:

$("column:nth-child(2n+1)").css("scroll", "otherDirection");
* {
  margin: 0;
  padding: 0;
}

#container {
  height: 100vh;
  display: flex;
  width: 70%;
  overflow-y: scroll;
}

img {
  width: 100%;
  display: block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<div id="container">

  <div class="column">

    Is this what your after?

    // Fallback for browsers that don't support CSS ScrollTimeline
if (!CSS.supports("animation-timeline: foo")) {
  // As we're about to shift content out of .columns, we need it to hide its overflow
  document.querySelector(".columns").style.overflowY = "hidden";

  // Set up timeline
  const timeline = new ScrollTimeline({
    scrollSource: document.documentElement,
    timeRange: 1,
    fill: "both"
  });

  // Loop all eligible columns
  document.querySelectorAll(".column-reverse").forEach(($column) => {
    // Flip item order in reverse columns
    $column.style.flexDirection = "column-reverse";

    // Hook Animation

    I’m not the best at css so I’m sure someone can come up with a better solution than this but hopefully, it will give you a starting point

    img {
  width: 100%;
  display: block;
}


/* column layout */

.columns {
  overflow: hidden;
  display: grid;
  grid-template-columns: repeat(5, 1fr);
  display: flex;
  height: 110vh;
  width: 100%;
  margin: 0 auto;
}

.column div {
  animation: slideDown 10s linear infinite;
}

@keyframes slideDown {
  0% {
    transform: translate3d(0, 0, 0);
  }
  100% {
    transform: translate3d(0, calc(-100% + 100vh), 0);
  }
}

.column-reverse div {
  animation: slideUp 10s linear infinite;
}

@keyframes slideUp {
  0% {
    transform: translate3d(0, 0, 0);
  }
  100% {
    transform: translate3d(0, calc(100% - 100vh), 0);
