Problem : I am very new to Bootstrap. I always wanted to work on bootstrap so now I want to use Bootstrap to make my interface for my program. I also added jQuery 1.11.0 to a <head> tag and thought that I can work with it, but when I tried to launch my web page ... I have tried with the copies hosted on many CDNs, but I am unable to get it to work. Can someone point out which step I am missing?
