Sorry, second post as in as many days...

Im looking to make a centered site, that has two columns (left and right) that contain images for background decoration and a content column.

What i dont understand is how i can make the left/right columns have hidden overflow whilst preserving the centered effect and preventing the overall positioning div to show.

learning from experience...ive done a little drawing!...it can be viewed here

Many thanks to you all for your patience with me!
