CMS page structure

Think of the page structure as three primary objects:

either:
[LEFT CONTENT RIGHT]
or:
[HEADER BODY FOOTER]

are defined as Primary, the other is contained by the middle element of the other.

i.e. [HEADER BODY FOOTER] defined inside CONTENT; or, [LEFT CONTENT RIGHT] defined inside BODY.

It is a column arrangement (not all columns need be used) that can be used to slice the site into "containers" that define how far the right icons are from the right edge, etc. i.e. to get stable pages (without having to fix it at every design change, requires you only change the BODY-CONTENT or the CONTENT-BODY module, and nothing else changes.

Think of coloured blocks. Take a big red one, and lay two skinny blue ones - one on each side. Now you can find a yellow one to cover the top and bottom. That is the expected behaviour of page structure. These are not rules, but guides to help to design rapid consistent pages without a CMS or a basic object strategy in a CMS.
