Assuming your build (as mine is) is minifying/combining all the css and js together and probably moving it somewhere else.
What do you do with the images/fonts? add a task to move them into the build script? just dump them in with the rest of your fonts/images? I’m leaning toward the latter, but I also don’t like separating my dependencies like that.. then if one of said files gets updated, it’s maybe not actually up to date anymore.
And then you just hope the authors of a library have been kind enough to include sass variables for any paths that you can override.
Does that make any sense?
