I applid a code from video lesson but the ruselt wasnt the same because we didnt use the same BS version , I use BS V4 and he use BS V3.3.4
when I changed it to the same BS it worked
is it necessary to use the same BS to get the same result

this is his code with Bootstrab V3.4.4

Yes some classnames are discontinued and there may be discrepancies between v3.x and v4.x. So use whatever version he is using.
