<h2 id=abstract>Abstract</h2>
<p>This specification defines Cascading Style Sheets level 2. CSS
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 simplifies Web authoring and
site maintenance.
<P>CSS 2.3 is the third revision of CSS level 2 [[-CSS2]]. It
corrects a few errors in CSS 2.2, the second revision of CSS
level 2.
It is <strong>not</strong> the latest version of CSS. See the "CSS Snapshot"
[[-CSS]] for an overview of specifications that make up the whole of
CSS.
<p>CSS level 2 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.
