ACTION-719 background

it has been hard for me to separate out some of the issues here
without doing 2 different suggested BPs
so I'll send along both 5.x.y_CSS and 5.9.4_Javascript
and folks should feel free to hack and slash
as I am still learning what the group needs to see

the idea here is that
both CSS and Javascript can be set up to
gracefully degrade or progressively enhance
based on client capabilities discovered at run-time
if the site and the pages are structured well
(separating content/presentation/behaviors)
