Full page header change - have got stuck - help please

[maison2]

Hi all,

I have just downloaded the Lifestyle theme for my site http://www.provence-life.com and followed the instructions to create a full page header from the thread http://www.studiopress.com/support/v...hp?f=16&t=5745, however, when I refresh the page, the header only covers half the page. I changed the header details in style.css and tried to remove the code listed in that thread in header.php, but it didn't work.

Could someone please tell me how to delete the part that still appears on the right of my header, so I can see the whole of my Provence Life header.

Thank you in advance for any help,
Antony
