I want to keep my “Discourse Forum Documentation” header on the left side of the page linked below from scrolling when a scrollbar appears. So I want the a scrollbar to move the links up and down but I want to keep the header in place.
I’m trying to mimic the functionality of the example Technical Documentation Page in this respect. I’ve tried playing around with the CSS but can’t figure out how to do this.
I needed the background-color and z-index so that there’s a white background “in front” of the navigation links that they disappear "behind’ when scrolling. Otherwise the navigation link text collides with the header.
