Oh wow, that looks like what I'm trying to achieve. Will have to give the solutions a try. Thanks!

Hi there. I've been looking at the ScrollTrigger plug-in to solve a UX problem but can't seem to get it working. I essentially want a sidebar, when taller than the viewport, to scroll along with the page both up and down, until its bottom edge comes up and hits the bottom edge of the viewport which then causes it to behave as fixed. The same should happen when you scroll upwards and the top of the sidebar comes down and hits the top edge of the viewport. Here's a crude diagram that might help visualize things. The content column is red, the sidebar yellow, and the viewport is black. In this case it's scrolling downwards, so just reverse it (or flip it upside down?) for scrolling upwards. In the attached pen, I'm only attempting this with the left (first) sidebar.
