The other day, Brad dropped me a message asking me about the topic of getting to know a brand new (specifically CSS) codebase. The kind of codebase that no one person truly understands any more; the kind of codebase that’s had a dozen different contributors over just as many years; the kind of codebase that’s never had a full-scale refactor or overhaul, but that’s grown organically over time and changed with new techniques, styles, and trends.

I can’t even imagine what it must be like to jump into a codebase like that.
