Which version of bootstrap does fcc teach

I kinda skipped over bootstrap course and just focused on all the JS stuff cause thats what i wanted 2 do. Now I need to focus a bit more on the design of my projects so does fcc teach version 3 or 4? if it teaches 3 could anyone recommend a place which teaches 4 for me please:)

many thanks

FCC is wonderful and teaches you version 4.

I think that FCC is the best online resource that I have ever used to learn anything. It’s very structured and gives me just enough information so I’m not stranded.

awsome thanks alot! gonna go back and learn it now xD
