Make appear the bottom of the page like that

[ungars]

  Hi,
  Can you tell me how to make appear the bottom of the home page like this exemple : http://www.troc-cadeaux.com/

  I would like to show some heading like that we can see on the link : troc cadeau, un site d' annonces gratuites, comment ça fonctionne...

  Thank you so much for your help, nice week end.
