In HTML, the <!DOC TYPE> means the type of HTML coding you are using. There are many different versions of HTML. This part of the code tells the web-browser how to format the page.
An HTML DOCTYPE defines which version of the language you are using, and let's the browser act accordingly. The DOCTYPE in an HTML document is an idea borrowed from XML. The DOCTYPE file defines the rules that the language has to follow. By making sure you've declared the doctype in an HTML document, you let the browser know how you're expecting that HTML to be treated. In an ideal environment, adding a doctype will allow you to be sure of exactly how the code will be rendered by the user's browser.
The first line of your HTML file should start with <!DOCTYPE HTML PUBLIC.... The first line of the actual HTML code begins with the <html> tag.
The whole Doctype tag in html 4 is shortened in html 5. Say in html 4 you saw some code like this at the top: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Now you just use <!DOCTYPE html>
An identifier in the HTML document, that tells to the browser which type of HTML it needs to use to show contents of that document. Specifying different versions of HTML will result in different behavior of the document. If the type hasn't been specified at the beginning of HTML document the browser might load it slowly or even with the errors. Usage: <!DOCTYPE HTML /*Here goes type of the document specification (DTD)*/>
There is not much in migrating from HTML to HTML5. You have to include the DOCTYPE in the html tag.
That's the DocType for HTML 4.01. It is normally used at the very beginning of an HTML 4.01 document to tell the browser what version of HTML it should use to render the page.

The term DOCTYPE tells the browser which type of HTML is used on a webpage. In turn, the browsers use DOCTYPE to determine how to render a page. Failing to use DOCTYPE or using the wrong DOCTYPE may load your page in Quirks Mode. AchieversIT Training Institute.

<tag>...</tag> For tags that open and close. Or <selfclosingtag> for tags that don't. Or <selfclosingtag /> if you're using XHTML **Note: neither of those are real HTML tags. For the first the paragraph tag <p>The content of the paragraph.</p> is a good example. For the second, <img src="image.jpg" alt="Image"> or <img src="image.jpg" alt="Image" />
doctype, html,head, body, and title
HTML does not have a DOCUMENT tag. The closest thing it has is DOCTYPE, which specifies which specification of HTML (there are several versions) is being used for that page.
A doctype is a header, so it should be placed at the top of the webpage. When writing HTML for a website, it should be placed directly above the tag.
A web page consists of a DOCTYPE, a HEAD element and a BODY element. The HEAD and BODY tags are optional in HTML but required in XHTML. The HEAD element must contain a TITLE element. The following is a valid page in HTML4.01: <!doctype html public "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <title></title> <p></p>
