Who can explain to me how I add a DOCTYPE to my html document?
The doctype declaration should be the very first thing in an HTML document, before the <html> tag.The doctype declaration is not an HTML tag; it is an instruction to the web browser about what version of the markup language the page is written in.The doctype declaration refers to a Document Type Definition (DTD). The DTD specifies the rules for the markup language, so that the browsers can render the content correctly.This is a great place to start DocType Infodink

Try not to create too many threads, or else people will just get confused - for example, from your thread here it would appear you got your DOCTYPE markup declaration working. At least modify the thread title to indicate it's solved.Anyway, the URL specified in the DOCTYPE is the location of the DTD (in this case, the HTML or XHTML one), and not the location of your website.

if you haven't time to learn how to write the doctype declarations perhaps you can visit other websites (more than one...) and view the source.What you should add at the beggining of your pages is what you find BEFORE the </head> tag. But be careful because there could be more than what you need and there could be some reference to something that you don't have in you web site (css file, for example).for example the code of this page (http://www.w3.org/QA/2002/04/valid-dtd-list.html) is like this:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head><meta http-equiv="content-type" content="text/html; charset=utf-8" /> <title>W3C QA - Recommended list of Doctype declarations you can use in your Web document</title> <meta name="Keywords" content="qa, quality assurance, conformance, validity, test suite, QA, quality, validation, html, validator, tools" /> <meta name="Description" content="W3C QA - List of valid Doctype declarations you can use in your document" /> <link rel="schema.DC" href="http://purl.org/dc" /> <meta name="DC.Subject" lang="en" content="QA, quality, validation, html, validator, tools" /> <meta name="DC.Title" lang="en" content="How to achieve web standards and quality on your website?" /> <meta name="DC.Description.Abstract" lang="en" content="A series of things to improve and achieve quality on your website." /> <meta name="DC.Date.Created" content="2002-04-08" /> <meta name="DC.Language" scheme="RFC1766" content ="en" /> <meta name="DC.Creator" content="Karl Dubost" /> <meta name="DC.Publisher" content="W3C - World Wide Web Consortium - http://www.w3.org" /> <meta name="DC.Rights" content="http://www.w3.org/Consortium/Legal/copyright-documents-19990405" /> <style type="text/css" media="all"> @import "/QA/2006/01/blogstyle.css"; </style></head>gabriele

Err, you don't really have to add everything you see in the <head> element of a document - the only required sub-element is <title>.

Thank you for all your answers about a DOCTYPE, but I still don´t know what do I have to write in my HTML document!
what are you talking about? and why are you making a new thread for this exact same topic? yessh....don't you have a webpage already made that you've been asking us about? What else are you looking for? didn't you get links for making a doctype? I believe I gave you an example of one in that thread; it's right in my signature.

Thanks! I have seen this topic several times, but in the examples they use URL´s and I need a DOCTYPE for my html document!

This often happens when developers design a page with no doctype and then add one AFTER they design the page. Browser manufacturers have agreed that pages with no doctypes should be rendered in the way it would have been rendered when HTML was new, way back in the 1990's. If you add a doctype to an old-style document, it will be rendered using the rules of the new doctype. The differences can be big. Internet Explorer certainly will render pages VERY differently than Firefox or Chrome. One of the reasons (not the best reason, but a very good one) for using a doctype is to make sure pages are rendered similarly by all browsers.The lesson here is this: add the doctype to your document BEFORE you write any HTML or CSS. You will get much better results than adding a doctype AFTER.

Doctype should have no relationship to the uploading process, so I'm not sure what you mean by that. You should know that the DTD you just posted is incomplete. The correct form looks like this:<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">You need both lines, and certainly you need to close the DOCTYPE tag.

<< "DOCTYPE #?" Topics merged >>Posting several topics for the same issue, and declining to accept the answer isn't going to change the answer. Keep posting in this topic if you have other issues in the understanding of how DOCTYPE works and why it fails with your current experiements.

Arguments of !DOCTYPE: This is my doctype statement : 

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">

What does the EN stand for at the en of the 3rd argument of !DOCTYPE. does it have any bearing on the language of the site If I want another language test do I need to change the EN there tooDerekvG
