Say I've an Top Of The Page, and within that page I've two sections (most likely two divs: tagline and services). Then, I must add static content inside individuals two sections (in type of Pages).
I am not so sure how you can "classify" these pages: (e.g. tagline and services), because pages don't ahve groups or tags.
I understand I must use
get_pages, but I am unsure crafting the entire function.
You can most likely use get_pages(), but this can be simpler: http://wordpress.org/extend/plugins/improved-include-page/
