Interactive Comments Section using Vite+React and Tailwind

First time using tailwind. I am having a hard time since I have to keep on checking the cheat sheet for the right syntax of the style.

I think I could've done better at the bar beside the replies by using :before and a little bit of manipulating the Y positions of it depending of the number of child but I don't know how to do it in tailwind. Any ideas are welcome.
