Need explanation on why I need a DTD
Posted on 2000-05-06
Can someone explain to me the advantages of using a DTD (Document Type Declaration)?
Do I need to go back to all of my old web pages and add this?
What is it supposed to do FOR my web pages or TO the web browser?
What happens if I don't have one?
Which numeric version should I use?
When I try to verify HTML at web sites, I am frequently told that the web page has problems even though it works, why?
