Please help me to change the AFP TLN width

Hello Experts

We are creating our custom AFP TLN for portal 7.3.

We are able to create successfully.

But  as we need to set out TLN  in our custom Ajax Framework Page.We are not able to do this.

Means we set width for masthead and footer as  80%. same  width we  try  to apply  for TLN  but its  not working means TLN is not aligned .

Actaully we want  our Masthead,TLN and Footer in one column lime.Out of this  Mashead and foorter  are align but TLN is not aligned.

Please  find the attached  screen shot  for the same.

Please  let me know  which propery i need to change inside the js  file  afpui_tln.
