Yes, I think that if you don't know CSS then learning that (rather than bootstrap 3 vs 4) is the right answer. None of these technologies are all that hard. Like, they are easy enough that I don't understand it as a question... if you know CSS/ SASS and that stack, they take about an hour to figure out the main points and get rolling. But even if you don;t know hardly any CSS then they still take like a day or so, and the principles are pretty much the same. And equivalent question is "should I learn Sublime or Notepad++". If you understand what they do, pick one and if it stops being a thing you can use for whatever reason then learn the other, because the difficult part of understanding what id going on with them is conceptually the same between them.
