Answer 1

You need to wrap the inputs in their own col-* classes like this..

  

      

          Quarter
          

           
          
      
      

          Address
          

           
          
          Addr. №
          

           
          
      
      

          Block name/Number
          

           
          
          Entrance
          

           
          
          Floor
          

           
          
          Apartment

Also, there is no col-sm-15 or col-sm-20 in Bootstrap
