This topic actually covers both design issues and javascript but a much stronger javascript implementation.

I realize a lot fo questions are always asked about cross-browser web programming however how do 'you' fix that. I am not asking for details but more for generalistics. Especially with the new browsers. For example do you have two or three designs. 1 for the old and hopefully someday DEAD nn4.7, early ie and the new ones. Or do you try to integrate a tonne of cross browser code??
