<h1>Style Activity Statement</h1>
<p>Many people are accustomed to style sheets in word-processing. W3C's
<a href="./">style sheets</a> offer extensive control over the
presentation of Web pages. The <em>Cascading Style Sheets</em>
(<a href="CSS">CSS</a>) language is widely implemented. It is playing
an important role in styling not just HTML, but also many
kinds of XML documents: <a href="../MarkUp">XHTML</a>, <a href="../Graphics/SVG">SVG</a> (<em>Scalable Vector Graphics</em>) and
<a href="../AudioVideo/">SMIL</a> (the <em>Synchronized Multimedia
Integration Language</em>), to name a few. It is also an important
means of adapting pages to different devices, such as mobile phones or
printers.</p>
<p>W3C is also developing the <em>Extensible Stylesheet Language</em>
(<a href="XSL/">XSL</a>, see the <a href="../XML/Activity">XML
Activity Statement</a>). XSL applies a “style sheet” to transform
one XML-based document into another. XSL and CSS can be <a href="CSS-vs-XSL">combined</a>.</p>
<p>W3C has a page on <a href="CSS/">CSS resources</a>, including
<a href="CSS/software#browsers">browsers</a>, <a href="CSS/software#editors">authoring
tools</a> and <a href="CSS/learning">tutorials.</a></p>
<h2>Highlights Since the Previous Advisory Committee Meeting</h2>
<p>The working group published four Recommendations (<a href="/TR/2011/REC-CSS2-20110607"><cite>Cascading Style Sheets
Level 2 Revision 1,</cite></a> <a href="/TR/2011/REC-css3-selectors-20110929/"><cite>Selectors

(CSS) Snapshot 2010</cite></a>), one Candidate Recommendation (<a href="/TR/2010/CR-css3-mediaqueries-20100727/"><cite>Media
Queries</cite></a>) and one or more drafts of several other CSS
modules (<a href="/TR/2011/WD-css3-fonts-20111004/"><cite>CSS Fonts
Module Level 3,</cite></a> <a href="/TR/2011/WD-css-device-adapt-20110915/"><cite>CSS Device

Level 4</cite></a>).</p>
<h2>Upcoming Activity Highlights</h2>
<p>The <abbr title="Working Group">WG</abbr> is working on test suites
for three of the specifications that are in <abbr title="Candidate Recommendation">CR</abbr> (<a href="/TR/2011/CR-css3-background-20110215"><cite>CSS Backgrounds
and Borders Module Level 3,</cite></a> <a href="/TR/2011/CR-css3-multicol-20110412"><cite>CSS Multi-column
Layout Module</cite></a> and <a href="/TR/2010/CR-css3-mediaqueries-20100727/"><cite>Media
Queries</cite></a>) and on new drafts of several other modules, with a
particular focus on the needs of EPUB, a standard for electronic books
created by the <a href="http://www.idpf.org/">IDPF,</a> with which W3C
has a liason.</p>
<p>Apart from the already mentioned Multi-column module, that focus
particularly affects <a href="/TR/2011/WD-css3-writing-modes-20110901/"><cite>CSS Writing
Modes Module Level 3, </cite></a> <a href="/TR/2011/WD-css3-text-20110901/"><cite>CSS Text
Level 3</cite></a> and <a href="/TR/2011/WD-css3-speech-20110818"><cite>CSS Speech Module,</cite></a> all of which are in advanced
state (the last one is already <abbr title="Last Call">LC</abbr>). But, it also implies work on the cluster of modules
about advanced layout (<a href="/TR/2010/WD-css3-layout-20100429"><cite>CSS Template Layout Module,</cite></a> <a href="/TR/2011/WD-css3-grid-layout-20110407"><cite>Grid
Layout,</cite></a> <a href="/TR/2007/WD-css3-grid-20070905"><cite>CSS Grid Positioning Module Level 3,</cite></a> <a href="/TR/2011/WD-css3-regions-20110609/"><cite>CSS Regions
Module</cite></a> and <cite>CSS Exclusions</cite> [unpublished]),
which still needs to be reduced down to just one or two much smaller
specifications.</p>
