Publishing issue

HI:
  i am kinda new to this one. i want to publish a page but not the whole of the page (which include by default apache logo, menu on left, body of page and footer) . All i want is that all my new addition to a newly created document in KUPU editor should only and only be publish. means a i want to publish my document EXCEPT menus,header logo and footer(which are included by default). only content of my document should be published, any one can tell me how can i do that
 thanks
