For my own instance, I guess I’d end up hacking the Inferno code as well, to add as much custom stuff as I wanted. While I agree that, at this stage of Lemmy development, Bootstrap is a decent choice, I’d say for a distant future something more flexible should be considered one day. I was trying to make stylable with a theme the left vertical lines that come with each comment, but now I’d rather give up. Those lines are set in the style attribute, thus overriding the theme, and every single existing theme has a border style for those, so any comment border style in main.css will be overridden by any theme that already comes with Lemmy. So I should either modify all the themes or leave things as is. That’s just an example of current limitations in flexibility, but anyway, I’d say for my own instance I’d end up hacking everything, accepting the fact that I should resolve merge conflicts on each pull from Lemmy master branch, and maybe making some PRs with some improvements.
