Looking for a simple "ChatLog" style Interview display

I’ve been pulling my hair out trying to add a simple conversational “chatlog” style layout for my interviews. I found this on GitHub but for some reason I cannot get it to work in a post at all. I’ve tried using {{ghost_head}} injection, linking to it externally in the html card, and just trying to put the css inline but nothing I do works… Am I just too smoothbrained for this?

Any breakdown of what may be happening or suggestions of a better method of doing this would be very VERY gladly accepted. I appreciate you all in advance!

Could you link what you’re looking at on GitHub or an example of the layout you’re trying for? I’m not sure I quite understand what you’re trying to do. :)

Oh my word, I was so burnt out that I did not post the link!

That Repo seems to be super simple and just pure CSS that I can just style but as I stated it just fails to render when I put the code in an HTML block…
