I ran into a road block (a victim of my own device) that looks to have been finally rectified. I am preparing to test my “1.2em” approach as soon as my dev install is finished rebuilding by entering the CSS into Customize
For whatever reason, I was thinking there was a way to pull in the CSS similar to how plugins can be added to app.yml so that they will appear in the UI and not need to be entered into Customize. I notice Sam’s files have .json and .scss files, but I’m sure I’m missing a crucial piece to the puzzle here somewhere.
