When I use the Boootrap 3.3.6 release, col-md-offset-* is working fine. However, in Bootrap 4, it in results failure.

Upon checking and checking, the naming conventions are apparently changed, as I checked it in the bootsrap.css file linked to it via maxcdn.

It works when I use: offset-md-* as the one I found in the CSS file. In the documentation though, it still says to use col-md-offset.

Also, it's not just in offset-md, also occurs in pull, push in the various grid sizes too:

I also posted the question on Stack Overflow http://stackoverflow.com/questions/37427245/bootstrap-4-accepting-offset-md-instead-col-offset-md-naming-convention-bug/
