Added css code for mobile compatibility of Scaffolds

Added:
  Css stuff to css scaffold template for the mobile compatibility.
  class named as attributes name to template index to get a pure css solution

Scaffolds are powerful to develop prototypes
with the evolution of mobile I think it makes sense to have
the possibility of making prototypes that are seen well on Mobile
