Here, in my question, remove the place in the bootstrap template , the answer (unacceptable) is in both conditions, i.e. span*this is an older bootstrap version and col-*it is a newer bootstrap version.
span*
col-*
So my question is, can I use both versions of the bootstrap style? Do I have to include both versions of bootstrap to work?
Or, if I turn on, could there be a conflict?
Or, can I merge both css files into one?
In fact, you can add your own CSS file that will flip all old CSS names into new definitions.
