thanks for all the replies.
taylorantone- you make a good point about not catering to javascript-disabled users. I had not thought about the situation that way.
However, research indicates that about 1 in 5 surfers are js-disabled. 20%. Big number. That stat may not be accurate, but still...
I had hoped to include a "little" js in my low bandwidth version, for such things as menus and linking positions of scrollable text areas <divs> with other objects.
It now seems that the correct strategy, for me, is to 1) create a low bandwidth version that is rail-thin, HTML-CSS only, and viewable also by PDA's, mobile phones, etc..., and 2) create a high bandwidth version that is all-out, javascript, Flash, 3d, the whole nine yards. The best of both extremes.
The only common element between the two versions being my never-changing content, which is what it is really all about.
thanks again for the replies, and please expect more questions about various things.
