I'm using bootstrap grid as shown below and I'm trying to centralize some divs. ( pic). I've tried everything {margin:0 auto; width:50% } etc etc but I can't work it out. It can't be that difficult to centralize some divs. What's the problem here? Please don't mark it as a duplicate. I've been researching the whole day, I just can't work it out. Thank you
