Abstract:
<p>This specification defines in general a subset of <acronym
title="Cascading Style Sheets">CSS</acronym> 2.1 [[!CSS21]] that is
to be considered a baseline for interoperability between
implementations of <acronym title="Cascading Style
Sheets">CSS</acronym> on constrained devices (e.g. mobile phones).
Its intent is <em>not</em> to produce a profile of <acronym
title="Cascading Style Sheets">CSS</acronym> incompatible with the
complete specification, but rather to ensure that implementations
that due to platform limitations cannot support the entire
specification implement a common subset that is interoperable not
only amongst constrained implementations but also with complete
ones. Additionally, this specification aligns itself as much as
possible with the <acronym title="Open Mobile
Alliance">OMA</acronym> Wireless <acronym title="Cascading Style
Sheets">CSS</acronym> 1.1 [[WCSS11]] specification. At the same
time, <acronym title="Open Mobile Alliance">OMA</acronym> is doing
alignment work in <acronym title="Open Mobile
Alliance">OMA</acronym> Wireless <acronym title="Cascading Style
Sheets">CSS</acronym> 1.2 [[WCSS12]]. It is aimed at aligning the
mandatory compliance items between <acronym title="Cascading Style
Sheets">CSS</acronym> Mobile Profile 2.0 and <acronym title="Open
Mobile Alliance">OMA</acronym> Wireless <acronym title="Cascading
Style Sheets">CSS</acronym> 1.2 [[WCSS12]].</p>
<p class=mtb><strong>This profile is obsolete. Please see the latest
<a href="https://www.w3.org/TR/CSS/" >CSS Snapshot</a> for the
specifications that make up CSS.</strong></p>
Status text:
<p><em>At this time, the CSS Working Group does not envisage further
work on this specification and does not plan to propose it as a W3C
Recommendation.</em></p>
</pre>
<h2 id=introduction>Introduction</h2>
<p>This document specifies a profile of <acronym title="Cascading Style Sheets">CSS</acronym> that is in general based on <acronym title="Cascading Style Sheets">CSS</acronym> 2.1 [[!CSS21]], but requires as well new features from <acronym title="Cascading Style Sheets">CSS</acronym> 3. In addition the document defines an <em class="rfc2119" title="Keyword in RFC 2119 context">OPTIONAL</em> feature set, that is suggested to be implemented by more advanced user agents.</p>
<h2 id=conf>Conformance</h2>
<p>
The key words of
descriptive assertions and RFC 2119 terminology. The key words "MUST",
"MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT",
"RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in
RFC 2119 [[!RFC2119]].
</p>
<p>
Since the goal of this specification is to define a baseline interoperability level, user
agents <em class="rfc2119" title="Keyword in RFC 2119 context">MAY</em> accept <acronym title="Cascading Style Sheets">CSS</acronym> documents conforming to <acronym title="Cascading Style Sheets">CSS</acronym> 2.1 or subsequent revisions of the <acronym title="Cascading Style Sheets">CSS</acronym>
family of Recommendations.
</p>
<p>
In order to conform to this specification, user agents, authoring tools, and content <em class="rfc2119" title="Keyword in RFC 2119 context">MUST</em>
conform to the <a href="http://www.w3.org/TR/CSS21/conform.html#conformance">Conformance</a>
and <a href="http://www.w3.org/TR/CSS21/conform.html#errors">Error conditions</a>
section of the <acronym title="Cascading Style Sheets">CSS</acronym> 2.1 specification [[!CSS21]], with the following modifications.
</p>
<ol>
<li>
Only features marked as supported in this specification are <em class="rfc2119" title="Keyword in RFC 2119 context">REQUIRED</em>.
Aside of the <em class="rfc2119" title="Keyword in RFC 2119 context">REQUIRED </em> feature set,
an additional <em class="rfc2119" title="Keyword in RFC 2119 context">OPTIONAL</em> feature set is given, that may be implemented by more advanced user agents.
This feature set is <em class="rfc2119" title="Keyword in RFC 2119 context">REQUIRED</em> by the <acronym title="Compound Document Formats">CDF</acronym> as in [[!WICDMobile10]].
Support for a larger set of <acronym title="Cascading Style Sheets">CSS</acronym> 2.1 is <em class="rfc2119" title="Keyword in RFC 2119 context">OPTIONAL</em>.
</li>
<li>
The requirement concerning which <a href="http://www.w3.org/TR/CSS21/media.html"><acronym title="Cascading Style Sheets">CSS</acronym> 2.1 media types</a>
are supported is tightened so that both the <code>handheld</code> and <code>all</code> media
types <em class="rfc2119" title="Keyword in RFC 2119 context">MUST</em> be accepted and processed. Other media types <em class="rfc2119" title="Keyword in RFC 2119 context">MAY</em> be accepted and processed as well.
</li>
<li>
The requirements that user agents <em class="rfc2119" title="Keyword in RFC 2119 context">MUST</em> make it possible to select an alternate style sheet
amongst those linked from the document, as well as provide for a way to turn off author style
sheets, are relaxed to be <em class="rfc2119" title="Keyword in RFC 2119 context">RECOMMENDED</em> behavior, but not <em class="rfc2119" title="Keyword in RFC 2119 context">REQUIRED</em>.
</li>
</ol>
<h2 id="selectors">Selectors</h2>
<p>
Selectors are defined in the <a href="http://www.w3.org/TR/CSS21/selector.html">Selectors</a>
chapter of the <acronym title="Cascading Style Sheets">CSS</acronym> 2.1 specification [[!CSS21]]. The following table identifies which selector

<p>
Properties are defined in several chapters of the <acronym title="Cascading Style Sheets">CSS</acronym> 2.1
specification [[!CSS21]] and in case of marquee properties in the <acronym title="Cascading Style Sheets">CSS</acronym> Marquee Module [[!CSS3MARQUEE]]. The following table identifies which properties
<em class="rfc2119" title="Keyword in RFC 2119 context">MUST</em> be supported amongst those defined by
<acronym title="Cascading Style Sheets">CSS</acronym> by setting the property as <em class="rfc2119" title="Keyword in RFC 2119 context">REQUIRED</em> in the table's last column.
Only properties that are part of the suggested feature set for advanced user agents are listed here as <em class="rfc2119" title="Keyword in RFC 2119 context">OPTIONAL</em>.
The property syntax is provided (expressed using the same <a href="http://www.w3.org/TR/CSS21/about.html#value-defs">value specifications</a>
as <acronym title="Cascading Style Sheets">CSS</acronym> 2.1) when it is subsetted from the original.
Limitations that apply to a property apply equally to its shorthand alternative.
