Two questions, actually, but they're both related, and very simple:
1. Is it possible to create a tableless site design under a 4.01 transitional (loose) doctype? (I know, strict is far better, but the site has well over 100 separate pages, all coded under loose mode long ago before I knew what CSS was, and I don't have either the time or the knowhow to properly transform it into strict mode.) I've done some fairly intensive Googling, and everything I've found that I could figure out with my limited skillset was demonstrated in strict mode.
2. If it is possible, is it worth the time and effort to spend reworking the code?
It's a basic 2-col, header and footer, design, nothing fancy, but if you care to look, here it is.
