Ah, you're doing what I did before when I made sloppy one-off adjustments, which is browsing the CSS that's minified in the built version of Soapbox on your server. It's possible to change things there but it won't persist through updates. What you need to do is basically fork the repo of the Soapbox version you use, find the file I posted and make the same adjustments to it in the source, and then build from the branch you committed your edits to yourself. There's instructions for building Soapbox manually for production in the readme, but later or whenever I'm free I can walk you through it more thoroughly if it's confusing. I needed one of my guys to help me make sense of it since I had little experience with node/yarn/etc. myself.
