links,
either within the current document or to other documents. Common examples of navigation sections
are
menus, tables of contents, and indexes.
THE "<section>"S"
The <section> HTML element represents a generic standalone section of a document, which
doesn't have a more
specific semantic element to represent it. Sections should always have a heading, with very few
exceptions.
THE "<span>"S"
The <span> HTML element is a generic inline container for phrasing content, which does not
inherently represent anything.
THE "<strong>"S"
The HTML element indicates that its contents have strong importance, seriousness, or
urgency.
Browsers typically render the contents in bold type
THE "<style>"S"
The <style> HTML element contains style information for a document, or part of a document. It
contains CSS,
which is applied to the contents of the document containing the <style> element.
