Code for Vertical Timeline on 7.1 (Solved)

I needed a simple, responsive vertical timeline for a site I'm building. I found this solution and thought I'd share for others who might be searching. I found this code and edited the HTML and CSS to suit: https://codepen.io/taraswenson/pen/xyMmox. HTML is pasted as a code block. CSS is added under Design > Custom CSS.

See comment below for the code I ended up using and screenshots.

I am getting a syntax error for line 1 after pasting into Custom CSS. Any idea why?

HTML must be placed in a Code Block. Only CSS can be added to Design > Custom CSS.

CSS

Note: I renamed all classes with a "timeline-" prefix as to not affect other Squarespace code. I also folded "box-sizing: border-box" into .timeline and .timeline-container, otherwise it will also affect other Squarespace code.
