<h2 id=abstract>Abstract</h2>
<p>Cascading Style Sheets (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 level 2 defines core functionality for CSS. It extends CSS
level 1 and is itself extended by various other CSS
specifications, called “CSS modules”.
<p>This note contains the <a href="https://www.w3.org/TR/CSS2/"
>latest revision of CSS level 2</a> with its <a
href="https://www.w3.org/Style/css2-updates/REC-CSS2-20110607-errata.html"
>errata</a> applied. As such, it is not a specification itself, but a
note for the convenience of testers and implementers. As the errata
become implemented and tested, new revisions of the CSS level 2
specification are expected to be published. And if those receive new
errata, this note will be updated, so as to always contain the latest
revision of CSS level 2 with all errata applied.
<P>See the <a href="https://www.w3.org/TR/CSS/" >CSS Snapshot</a> for
an overview of specifications that make up the whole of CSS.
