Request for help on my ruby-on-rails project at cloud9 IDE

Hello fellow developers.I am building a Saasapp at cloud9 IDE.I have built the home page and about page successfully.

After branching to another branch entitled ‘contacts’,i get a problem with bootstrap grid system where i specified four columns for the contact form to reduce to.May someone kindly look at the project at the link below and help me detect and correct this problem since the form doesn’t conform to col-md-4.

Here is the link and thank you:
