This is a CSS style specification method is only used with HTML. An
entire style sheet can be embedded in an HTML document using the
STYLE[-->Index DOT Html] element contained
within the HEAD block. The complete range of CSS
syntax is allowed in this inclusion method - the style information
is not explicitly tied directly to the document's elements, so
Selector syntax is used to
specify what styles attach to which portions of the document tree (the
same as with External Style Sheets, but in this case the style sheet
is contained within the document itself.)
Unlike external style sheets, this method can only specify style
information for the current document. If equivalent style rules are
specified in an external and embedded style sheet, the embedded style
sheet rule will have higher precedence.
HTML Inclusion Method
In HTML, an Embedded Style Sheet is specified using the
STYLE[-->Index DOT Html] element
within the HEAD element block. For backward compatibility
with browsers that do not understand style sheet syntax, the entire
contents of the Style element may be embedded in an HTML comment (<!-- -->)
