Safari black screen; Firefox OK

Question

The "black screen" posts are old, but nothing I read applies.  [My Safari works with kuler.adobe.com, as discussed on old posts]  I fixed some things that were flagged on Browser compatibility (old browsers) and did validation tests, and the page in question just passed.  I'm using Mac 10.6 (Intel) and Safari 4.0.3.  My background colors are black, but I doubt that's the cause of a totally black screen.  Safari has some "developers' tools, but nothing made any difference.
The page I'm looking at (or trying to look at) is http://www.jfigueras.com/newsite/addedpage.html
This is an html version of my template.  The links will not work because I've not uploaded the linked pages. 
All ideas welcome.  Joann

Thanks for checking and for sending me in the right direction.  Although this computer is about a month old and came with software, it apparently has the wrong Safari and needs a system update.  I won't be in a place to do the system update till next week (update time here: 15 hours).  Then I can install the updated Safari and hope the black screen is gone.  Very good news that you saw the html on your browsers.
I used your http://jigsaw.w3.org/css-validator/, which found things not found by http://validator.w3.org/#validate_by_input
... now if I could get my links to keep the colors assigned in their classes, I would be near the end.
Thank you,  Joann
