Sometime back I had raised a query with respect to my code. It was a simple DHTML menu, I alwaays got few negetive response coz few of them were not able to see the output of my code. The reason was it doesnt work on on Stricter doc type.
I had a similar situation at office. We migration exercise where a site's underlying technology was shifted from one to another, from epicentric to weblogic portal. When the constructed pages from weblogic were viewed, it was totally out of sync. All alignment were gone for a toss. After a long investigation, it was found earlier the doctype was "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">" and now it is on STRICT.DTD.
I would like to know
1. which is the right DOCTYPE to be used.
2. Can I get a listing of all HTML tags compatible to all DOCTYPE
3. Are there any basic Do's and Dont's where in this kind of compatibility problems can be avoided.
If not by explanation if any one can guide me with URLs from where I can get these information it would be nice
Thanks a lot
