2) What is the <!DOCTYPE> ? Is it necessary to use in HTML5 ?
Ans:
The <!DOCTYPE> is an instruction to the web browser about what
version of HTML the page is written in. AND The <!DOCTYPE> tag
does not have an end tag and It is not case sensitive.
The
<!DOCTYPE> declaration must be the very first thing in HTML5
document, before the <html> tag. As In HTML 4.01, all <!
DOCTYPE > declarations require a reference to a Document Type
Definition (DTD), because HTML 4.01 was based on Standard Generalized
Markup Language (SGML). WHERE AS HTML5 is not based on SGML, and
therefore does not require a reference to a Document Type Definition
(DTD).
