Hello guys 
I was thinking that many of you wonder what a Doctype is.So i decided to make a useful tutorial telling what a doctype is,what types of doctype are in the net and how we use it.Lets begin .
What we quote above is the main structure of an HTML document(yes i know i havent included style & head tags so dont get crazy
).The first thing we see is the Doctype.
So,what is a Doctype?
The Doctype is an HTML Declaration that informs browsers what type and version of markup language your page is written in.However,a Doctype is not an HTML tag.The 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.
What are the available Doctypes?
There are 3 types of Doctypes:
* STRICT
* TRANSITIONAL
* FRAMESET
They are the following:
HTML 4.01 Strict
This DTD contains all HTML elements and attributes, but does NOT INCLUDE presentational or deprecated elements (like font). Framesets are not allowed.
HTML 4.01 Transitional
This DTD contains all HTML elements and attributes, INCLUDING presentational and deprecated elements (like font). Framesets are not allowed.
HTML 4.01 Frameset
This DTD is equal to HTML 4.01 Transitional, but allows the use of frameset content.
XHTML 1.0 Strict
This DTD contains all HTML elements and attributes, but does NOT INCLUDE presentational or deprecated elements (like font). Framesets are not allowed. The markup must also be written as well-formed XML.
XHTML 1.0 Transitional
This DTD contains all HTML elements and attributes, INCLUDING presentational and deprecated elements (like font). Framesets are not allowed. The markup must also be written as well-formed XML.
XHTML 1.0 Frameset
This DTD is equal to XHTML 1.0 Transitional, but allows the use of frameset content.
XHTML 1.1
This DTD is equal to XHTML 1.0 Strict, but allows you to add modules (for example to provide ruby support for East-Asian languages).
HTML 5
HTML 5 also comes with a brand new and more simple Doctype:
