Unit I Web Work 3
I found several articals about DHTML standards and what it
is. W3C was
founded by Tim Berners-Lee the father of the web. W3C issues no
real
standards but only reccomdations and the browser programmers go
along with
them or they dont.
W3C describes the latest version of CSS as this: This specification
defines
Cascading Style Sheets, level 2 (CSS2). CSS2 is a style sheet
language that
allows authors and users to attach style (e.g., fonts, spacing,
and aural
cues) to structured documents (e.g., HTML documents and XML applications).
By separating the presentation style of documents from the content
of
documents, CSS2 simplifies Web authoring and site maintenance.
CSS2 builds on CSS1 (see [CSS1]) and, with very few exceptions,
all valid
CSS1 style sheets are valid CSS2 style sheets. CSS2 supports media-specific
style sheets so that authors may tailor the presentation of their
documents
to visual browsers, aural devices, printers, braille devices,
handheld
devices, etc. This specification also supports content positioning,
downloadable fonts, table layout, features for internationalization,
automatic counters and numbering, and some properties related
to user
interface. See this URL for documentation:

In Netscape's report, Netscape reports that Communicator supports
two types
of style sheet syntax. It supports style sheets written in cascading
style
sheet (CSS) syntax. It also supports style sheets written in JavaScript
that
use the document object model. In the document object model, a
document is
an object that has properties. Each property can in turn be an
object that
has further properties. The following URL describes style sheets.

When you define a style sheet, you must declare its type as
either
"text/CSS" or "text/JavaScript". To try to
keep things straight, this manual
uses the term CSS syntax to refer to the syntax for style sheets
whose type
is "text/CSS". It uses the term JavaScript syntax to
refer to the syntax for
style sheets whose type is "text/JavaScript". Netscape
suggests that if
you'd like to see the original specification for style sheets
as authored by
the World Wide Web Consortium, you can go to:
http://www.w3.org/pub/WWW/TR/REC-CSS1.
In the Microsoft website regarding CSS, Microsoft write in
a report that
with the final release of Internet Explorer 4.0, it will fully
support
Cascading Style Sheets (CSS), which were introduced in Internet
Explorer
3.0. The extended control that CSS gives over Web page presentation
and
layout in this latest release of the browser will make page control
easier.
CSS, for the uninitiated, is a standard for formatting Web
pages that goes
well beyond the limitations of HTML. Promulgated by the World
Wide Web
Consortium (W3C), the Internet's standards body, CSS extends HTML
with more
than 70 style properties that can be applied to HTML tags. With
CSS, Web
developers have at their disposal a wealth of additional formatting
options
for color, spacing, positioning, borders, margins, cursors, and
more.
Internet Explorer 4.0 includes support for the CSS2 specification
, and for
the W3C HTML 4.0 specification , which includes inline styles.
For example,
the developer can apply the "cursor" property to any
HTML element, causing
the mouse pointer to change when passed over the element.For more
