hmmm - how do I .... (have in effect a HUGE popover)

[TheeeDragon]

I have a few single paragraph blocks of text
some need additional data
and I desire it to be accessed via <more>
(look bottom right of text under capital services)



I can make this a link to a separate page that is not part of the nav buttons
but I want something more elegant
eg a POPup box == but that is not big enough
maybe some form of a layer
(i have not learned to use layers at all)
or maybe a page-wide block of text that will PUSH the rest of the page down
(like a typical accordion FAQ)

if my request is not clear enough
I can add some more sample photos of what I want
