<!DOCTYPE documentType>
Attributes
The documentType attribute that you can see in the preceding code lets the browser know the type of document you will use.
Description
HTML5 has a simple document type declaration, <!DOCTYPE html>. This lets the browser know that the document is HTML5. The previous versions of HTML needed a formal definition of the version being used, but HTML5 has removed this for simplicity.

Here is an HTML5 declaration:
<!DOCTYPE html>
