<h2>Scope</h2>
<p>Cascading Style Sheets (CSS) is a style sheet language that allows
authors and users to attach style (e.g., from fonts and spacing to
filter effects and style animations) to structured documents and
Web applications. By separating the presentation style
from the content, CSS simplifies Web authoring
and site maintenance. It supports media-specific style so that authors
may tailor the presentation to different devices and capabilities.
</p><p>The CSS WG develops a single deliverable, the CSS specification. It consists of the following, somewhat independent
technologies, all of which are in scope for the CSS Working Group:
</p><ul>
<li>A <strong>syntax</strong> for associating information
with elements in a structured resource, in particular HTML
and SVG documents. The main part of the syntax consists of
rules that associate properties + values with selectors
where the selectors are expressions that match elements in
the structured document, based on their position in the
document or based on other information about the elements
(their type, what the user has done with them, etc.)
</li><li>A <strong>processing model,</strong> referred to as
“cascading and inheritance,” that ensures that, given
one or more style sheets and a structured document, each
element in the document is associated with the full set of
properties and values, no matter how short the style sheets
or how long the document.
</li><li>A <strong>rendering model,</strong> part of which is a
model of typography, i.e., a layout model for text
documents, possibly with embedded other objects and
possibly involving several documents simultaneously.
The model describes blocks and lines of text, characters,
columns, colors, dynamic effects, etc. It also
includes the presentation and behavior of UI widgets. CSS's
influence over UI controls is limited to defining the look of controls in various states during
interaction (valid/invalid, required, inactive, etc.),
hiding/unhiding, and other local behaviors, but CSS does
not itself change the state of elements and does not define
how (form) elements interact with a server. (The general
principle is that CSS can enhance the user's interaction
with a document, but the document should ideally be
functional without it.)
</li><li>The <strong>CSS Object Model,</strong> a set of standard
APIs, to which libraries can be written for manipulating
style sheets and documents with associated style
information.
</li></ul>
<p>
The CSS WG not only develops CSS, but also checks that
properties needed by other working groups and which could
occur in a style sheet together with CSS properties, are
compatible with CSS in general and consistent in their naming
schemes. This affects properties such as those of SVG and
Device Independence (such as media features).
</p>
<p>
Part of the work of the working group is also to develop
test suites for the various specifications it publishes.
</p>
<p>
Another part is to maintain errata and, when needed, publish
revised versions of the various specifications.
</p>
<!-- <div id="section-out-of-scope">
<h3 id="out-of-scope">Out of Scope</h3>
<p>The following features are out of scope, and will not be addressed by this Working Group.</p>

<section id="deliverables">
<h2>
Deliverables
</h2>
<p>There is a single deliverable, the CSS specification. The CSS specification is large, and is divided into a series of modules.</p>
<p>More detailed milestones and updated publication schedules are available on the <a href="https://www.w3.org/Style/CSS/current-work.en.html">group publication status page</a>.</p>
<p><i>Draft state</i> indicates the state of the deliverable at the time of the charter approval. <i>Expected completion</i> indicates when the deliverable is projected to become a Recommendation within this charter period. Deliverables without expected completion dates are not projected to become Recommendation within this charter period.</p>
<p>This list of modules is not exclusive: The WG may also create new CSS modules, within its scope. Also, it may split or merge CSS modules. If no participant in the group believes a proposed module is out of scope, and the group has consensus to add it, the group may add a new module. If the participants who object sustain their objection after discussion, a re-charter to clarify the scope may be needed.</p>
