This tag specifies that the webpage is written
in HTML. It appears at the very first and last line
of the webpage. It is mainly used to show that
the page uses HTML5 – the latest version of
the language. Also known as the root element,
this tag can be thought of as a parent tag for
every other tag used in the page.
