>All posts have their rectangle spread through all the page, from one side to the other
You should be able to do this
>All posts are surrounded by a graphic of some kind, think of it as a colored box with an extra detail at the upper and lower sides
You mean a graphic above and below each post? This might be possible to do, not exactly sure what the best way to do it is, maybe messing with the padding on top and bottom and just having one image for background with graphic on top and bottom (maybe transparent in the middle)
>The very top and very bottom of the page (meaning just below the overboard section but above the manage board section) has a similar graphic
Possibly similar to above, messing with the padding for top/bottom
>Possibly, said graphic should be randomized among a few
You might have to be some kinda magician to make this work without altering the site via admin access
>Additionally, is there a way to change IDs to have a given graphic enclose them?
If you mean the colored poster ID then no, I tried to style that but was unable to, CSS standards aren't at that level (at least not yet, not sure if they will be)
