The location of a metadata
profile for this document.
Not commonly used.
Defines the header of the
HTML file. Houses
information-based elements,
such as base, link, meta,
script, style, and title.
This is a required element for
XHTML web pages. (It??™s
optional for HTML, but
implied when absent.
However, it??™s good practice
to always include a head
element in web pages.)
(required)
Defines enclosed contents as
a heading. Available levels are
1 to 6. Note that although h4
through h6 tend to be
displayed smaller than body
copy by default, they are not
a means to create small text;
rather, they are a way to
enable you to structure your
document. This is essential,
because headings help with
assistive technology, enabling
the visually impaired to
efficiently surf the Web.
