Improvement: header&footer

[Marooned]

One of the things I do when playing wiht CSS settings is to add border: solid 1px red; to each of the CSS selectors I'm trying to play with.

While this is nice and easy, I would suggest using outline instead of border, as border changes various things like sizes of bounding box and breaks margin collapsing so with border you might have all ok, then remove the border and break your precise layout. outline does not bring those issues.
