I'm not familiar with bootstrap so you will need to explain what you have done to make all this happen so that I don't have to learn bootstrap from scratch before offering help. I don't see any logical code in the page that will create what you want unless it's all in the scripts.
It seems that bootstrap has complicated (as far as debugging goes) what is essentially quite a simple layout. If you can define where and what routines you have used to make this all happen then we may be able to help a little easier.
Isn't it strange that the only question gone unanswered here is the one where the op is using bootstrap which is supposed to simplify development but instead seems to make it almost impossible to debug.
