    What are the benefits and negative to passing a document type validation such as

    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    validator.w3.org

    The benefit of having a doctype is that it let's your browser:
    1.) Be validated
    2.) Keep IE out from quirksmode
    3.) Gives your design a fair ground...(at least)

    Negative effects....for me is none..except that it lets you work twice as much as you're working just to fulfill the same rendering on different browsers :D

    I guess DTD has no ill effects...Why would the standard require a DTD in every page when it has to bring ill effects :roll:

    Not a comment...but indeed a useful part of the page....a semantical way of proper coding..It's importance is equal as to having a body tag in your HTML :D

    There are a number of articles that tackle regarding DTD..and the validation:
