I just finished a redesign of this site for one of our stations.
Some of the issues I tried to address are:
scalabilty (text resizing - I'm using ems now instead of fixed [pixels])
semantics (better use of...)
separation of style and content
elimination of bulky JS for menus (all suckerfish and lists now)
I think I did a pretty good job of each but, of course, I'm sure there is some room for improvement.
I'm not crazy about white text on a dark background but I was over-ruled on that one so I tried to make it as readable as I could.
It all validates as xhtml 1.0 Trans (except the news.php page - grrrr)
I would appreciate any comments or suggestions altho I'm already cringing.
