information
A valid HTML document declares what version of HTML is used in the document.Strict DTD includes all elements and
attributes that have not been
deprecated or do not appear in frameset documents.Frameset DTD includes
everything in the transitional DTD plus frames as well.As of the 24 December version of HTML 4.Any changes to future HTML 4 DTDs will not invalidate documents that
conform to the DTDs of the present specification.The HTML Working Group
reserves the right to correct known bugs.Software conforming to the DTDs of the present specification may ignore
features of future HTML 4 DTDs that it does not recognize.This means that in a document type declaration, authors may safely use a
system identifier that refers to the latest version of an HTML 4 DTD.Authors
may also choose to use a system identifier that refers to a specific (dated)
version of an HTML 4 DTD when validation to that particular DTD is required.W3C will make every effort to make archival documents indefinitely available at
their original address in their original form.The
value of this attribute specifies which HTML DTD version governs the current
document.This attribute specifies the location of one or more meta data profiles,
separated by white space.For future extensions, user agents should consider
the value to be a list even though this specification only considers the first
URI to be significant.The
HEAD element contains information about the current document, such
as its title, keywords that may be useful to search engines, and other data
that is not considered document content.User agents do not generally render
elements that appear in the
HEAD as content.The TITLE element is not considered part of the flow of text.This attribute offers advisory information about the element for which it
is set.Please consult an element's definition to
verify that it supports this attribute.For
example, a profile designed to help search engines index documents might define
properties such as "author", "copyright", "keywords", etc.LINK elements in the document head.This attribute identifies a property name.This specification does not
list legal values for this attribute.HTTP servers use this attribute to gather information for HTTP
response message headers.The
META element can be used to identify properties of a document (e.This specification does not define a normative set of
properties.Authors should not use
this technique to forward users to different pages, as this makes the page
inaccessible to some users.PDF), and, when the
document is part of a collection, links to an appropriate starting point for
browsing the collection.META declaration to include a
PICS 1.As a globally unique name.For instance, search engines could provide
an interface for searching through catalogs of HTML documents, where these
documents all use the same profile for representing catalog entries.This specification does not
define formats for profiles.At times, such
additional information may be critical, as when meta data may be specified in
different formats.October 1997 or 10 September

value.The
value of this attribute is a URI that designates an image resource.This
attribute sets the color of text marking visited hypertext links (for visual
browsers).This
attribute sets the color of text marking hypertext links when selected by the
user (for visual browsers).For audio user agents, the same content
may be spoken.It sets the background
color of the canvas to white, the text foreground color to black, and the color
of hyperlinks to red initially, fuchsia when activated, and maroon once
visited.This attribute assigns a name to an element.Any number of elements may be assigned the same class name or names.For general purpose processing by user agents (e.HTML pages into a database, translating HTML
documents into other formats, etc.The
class attribute, on the other hand, assigns one or more class names
to an element; the element may be said to belong to these classes.As a style sheet selector (when an
author wishes to assign style information to a set of elements).For general purpose processing by user agents.Messages appear in both English and French versions.Authors may make further use
of the
id attribute to refine the presentation of individual messages, make
them target anchors, etc.Almost every HTML element may be assigned identifier and class
information.The
id attribute shares the same name space as the
name attribute when used for anchor names.Please
consult the section on anchors with
id for more information.Inherent in this structural distinction is the idea that
block elements create "larger" structures than inline elements.Style sheets provide the means to
specify the rendering of arbitrary elements, including whether an element is
rendered as block or inline.In some cases, such as an inline style for list
elements, this may be appropriate, but generally speaking, authors are
discouraged from overriding the conventional interpretation of HTML elements in
this way.See the section on the
effect of style sheets on bidirectionality for more information.DIV) but impose no other presentational idioms on the
content.HTML to their own needs and tastes.Since HTML does not include elements that
identify objects such as "client", "telephone number", "email address", etc.For another example of usage, please consult the example in the section on
the class and id
attributes.Heading information may be used by user agents, for example, to construct a
table of contents for a document automatically.DIV element to associate a
heading with the document section that follows it.Doing so allows you to
define a style for the section (color the background, set the font, etc.In this section, we discuss the lesser known forest elephants.They accept H1 H2 H1 while they do not accept H1 H3
H1 since the heading level H2 is skipped.The
ADDRESS element may be used by authors to supply contact information
for a document or a major part of a document such as a form.
