old question:

note: old question, please ignore.
working sample application ng-flow file upload. moved developed parts colleague's environment using bootstrap css. noticed , feel changed on environment.

i realized colleague using css file:

http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css

and using css file came download:

http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css

and both work fine, have clear differences on how , feel , how layout presented.

i included both, , seems application still working fine, , , feel merged.

i wondering if there documentation explains differences , how decide 1 use.

appreciate feedback.

the reason different they're referring different versions of bootstrap - version 3.3.7 vs version 2.3.2. (the other difference files hosted.) 3.3.7 more recent 2.3.2.

generally, want use recent version available whatever libraries you're including, unless need stay compatible older one. shouldn't include both, though; that's going have users downloading lot of redundant css.
