There's also conditional imports which allow you to say hey only import this thing if it supports using the supports function. That means that you can quickly and easily keep some of your fallback stuff separate from your Experimental stuff. So maybe the solution to css variables not being working Is you just recompile it whenever variable changes? That's probably a really bad idea But it may be good. If it's fast enough, maybe like it's it says it is 4.16 milliseconds to minify bootstrap, which is 10,000 lines. Okay I don't know. There's probably not a good idea. You want to give that our shot?
