<h2 id=abstract>Abstract</h2>

<p>This specification defines Cascading Style Sheets, level&nbsp;2
revision&nbsp;1 (CSS&nbsp;2.1). CSS&nbsp;2.1 is a style sheet language
that allows
authors and users to attach style (e.g., fonts and spacing) to
structured documents (e.g., HTML documents and XML
applications). By separating the presentation style of documents from
the content of documents, CSS&nbsp;2.1 simplifies Web authoring and
site maintenance.

<P>CSS&nbsp;2.1 builds on CSS2 <a href="refs.html#ref-CSS2" rel="biblioentry" class="noxref"><span class="informref">[CSS2]</span></a> which builds on CSS1 <a href="refs.html#ref-CSS1" rel="biblioentry" class="noxref"><span class="informref">[CSS1]</span></a>.
It 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. It also supports
content positioning, table layout, features for internationalization
and some properties related to user interface.

<p>CSS&nbsp;2.1 corrects a few errors in CSS2 (the most important
being a new definition of the height/width of absolutely positioned
elements, more influence for HTML's "style" attribute and a new
calculation of the 'clip' property), and adds a few highly requested
features which have already been widely implemented.
But most of all CSS&nbsp;2.1
represents a "snapshot" of CSS usage: it consists of all CSS features
that are implemented interoperably at the date of publication of the Recommendation.

<p>CSS&nbsp;2.1 is derived from and is intended to replace CSS2. Some
parts of CSS2 are unchanged in CSS&nbsp;2.1, some parts have been
altered, and some parts removed. The removed portions may be used in a
future CSS3 specification. Future specs should refer to CSS&nbsp;2.1
(unless they need features from CSS2 which have been dropped in
CSS&nbsp;2.1, and then they should only reference CSS2 for those
features, or preferably reference such feature(s) in the respective
CSS3 Module that includes those feature(s)).

<p>This document was produced by a group operating under
the <a href="http://www.w3.org/Consortium/Patent-Policy-20040205/">5 February 2004 W3C
Patent Policy</a>. W3C maintains a <a rel="disclosure"

An individual who has actual knowledge of a patent which the
individual believes
contains <a

<p>The Working Group has created a <a href="/Style/CSS/Test/">test
