Hey I am trying to achieve the same thing and am getting hung up. Saw that you were able to figure it out! I’ve adding the code to the footer and changed the class from “.course-sidebar-wrapper” to mine which is “.sticky-side-bar-wrapper”. Did you do any other edits to the code to get it to work? This is what I put in my footer:
<style>
.sticky-side-bar-wrapper {
position: -webkit-sticky;
position: -moz-sticky;
position: -ms-sticky;
position: -o-sticky;
position: sticky;
top: 50px;
}
</style>
