fixed all errors but 2 types, read below.

I got rid of all errors but two that I will need guidance on:

Says many times that height and width cannot use % tags but when
researching fluid design this is the common practice. I tested it in
IE, firefox, safari and opera and it worked in all
Line 60 says divs can not accept white-space:pre but it is how it is
shown on the w3 website.

I'm more then willing to correct these but would like to know how since
both errors seem to be considered best practice from what I've seen.
