to have the left and right spacers expand with the content they
have to be placed inside the content div and the give them a height
value of 100%.
( need to be inside because the height is inherited from the
i had to play with the float attributes in the divs that are
contained within the .content class to get them to sit correctly.
also i had to change the h1 in the .insert div to h2 otherwise
it will inherit the other h1 values.
one other thing is the green bottom border extends past the
left/right spacers. is this ok?
it may be difficult to have it so the border does not extend
to the spacers ( easy to put in there but making sure its
always at the bottom of the content div could be difficult)
