Need an explanation of "document type declaration". I have had about 70-80 html pages on the internet in 3 different websites, all without a document type declaration. I don't"
1)understand the function/purpose of such a declaration and
2)don't know how to determine which of the following ones apply to me:
--- for HTML 4.01 Strict documents, <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "
http://www.w3.org/TR/html4/strict.dtd"> should be the first line.
--- For HTML 4.01 Transitional documents, the first line should be <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "
http://www.w3.org/TR/html4/loose.dtd">.
--- For HTML 4.01 Frameset documents, the first line should be <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "
http://www.w3.org/TR/html4/frameset.dtd">. Thanks
