<h2 id="section-overview">Overview</h2>
<p>This document specifies a profile of the Cascading Style Sheets level 2 (CSS2) and CSS3 module: Color specifications appropriate for TV devices such as set top boxes or integrated interactive television sets that display their output on a television screen. Conformance to this profile means that a user agent supports, at minimum, the features defined in this specification. This subject is addressed in <a href="#section-conformance">Section 2, Conformance,</a> below.
</p>
<p>As defined in [[!CSS2]]:</p>
<blockquote>
<p>CSS2 is a style sheet language that allows authors and users to attach style (e.g., fonts, spacing, and aural cues) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS2 simplifies Web authoring and site maintenance. CSS2 builds on CSS1 (see [[!CSS1]]) and, with very few exceptions, all valid
CSS1 style sheets are valid CSS2 style sheets. CSS2 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.</p>
</blockquote>
<p>In summary, CSS2 specifies how developers can author style sheets for presenting documents across multiple devices and media types. While this is very important, it is also important that authors have an understanding of what features are supported on these different devices. Likewise, it is important that similar devices operate in a similar manner. Otherwise, authors will need to develop style sheets for each version of each device -- raising the cost of content development and decreasing interoperability.</p>
<p>The CSS TV Profile specifies a conformance profile for TV devices, identifying a minimum set of properties, values, selectors, and cascading rules. The resulting CSS TV Profile includes the vast majority of CSS1, portions of CSS2 and CSS3 module: Color. The CSS TV Profile is a proper superset of the CSS Mobile Profile, with the use of the 'tv' media type instead of the 'handheld' media type.</p>
<!-- ******************** -->
<!-- CONFORMANCE -->
<!-- ******************** -->
<h2 id="section-conformance">Conformance</h2>
<p>The primary role of a profile is to define a subset of features that provides a minimal guarantee of interoperability. In the case of the CSS TV Profile, this guarantee is that a conforming user agent will support the features defined in this specification following the CSS2 conformance clause ([[!CSS2]] Section 3.2), recast and summarized below:</p>
<ol>
<li>A CSS TV Profile conforming user agent (TV-UA) MUST support the <em>all</em> and <em>tv</em> CSS2 media types. A TV-UA MAY support other CSS2 media types, as well.</li>
<li>For each source document, a TV-UA MUST attempt to retrieve all associated style sheets that are appropriate for the supported media types.</li>
<li>A TV-UA MUST parse the style sheets according to this specification. In particular, the TV-UA MUST recognize all CSS TV Profile at-rules, blocks, declarations, and selectors. If a TV-UA encounters a property that applies for a supported media type, the TV-UA MUST parse the value according to the property definition. This means that the TV-UA MUST accept all valid values and MUST ignore declarations with invalid values. TV-UA MUST ignore rules that apply to unsupported media types.</li>
<li>For each element in a document tree, the TV-UA MUST assign a value for every applicable property according to the property's definition and the rules of cascading and inheritance.</li>
<li>If the source document comes with alternate style sheets (such as with the "alternate" keyword in HTML 4.0 [HTML40
823C
]), the TV-UA SHOULD allow the user to select one from among these style sheets and apply the selected one.</li>
</ol>
<p>As with CSS2, there are qualifications to this conformance clause:</p>
<ol>
<li>Values MAY be approximated when required by the TV-UA.</li>
<li>The inability of a TV-UA to implement part of this specification due to the limitations of a particular device (e.g., a TV-UA cannot render colors on a monochrome monitor or page) SHALL NOT imply non-conformance.</li>
</ol>
<p>It is recommended that authors use this conformance profile to take advantage of forward compatibility. Authors should be able to use style properties with an understanding that the cascading rules are processed correctly and that unknown properties and values are ignored. For example:</p>
<div class="code-example">
<pre>
h3 {
display: inline;
display: run-in;
}
</pre>
</div>
<p>A TV-UA that can process the 'run-in' value for the 'display' property will
accept the first display declaration and then "write over" that value with
the second display declaration. A TV-UA that cannot process the 'run-in' value
will process the first display specification and ignore the second
display specification.</p>

<!-- SELECTORS -->
<!-- ******************* -->
<h2 id="section-selectors">Selectors and at-rules</h2>
<h3 id="selectors">Selectors</h3>
<p>
In CSS2, pattern matching rules determine which style rules apply to elements
in the document tree [[!CSS2]].
</p>
<p>The following table summarizes CSS TV Profile selector syntax.
In addition to these selectors, the CSS TV Profile includes the
CSS2 grouping mechanism (See [[!CSS2]] Section 5.2.1).</p>
<div class="note"><p>
<em><strong>Note.</strong>
Unsupported selectors are parsed as invalid (which would affect valid selectors in the same group),
the same as if a purely CSS1 UA were to encounter selectors new in CSS2.
Of course a TV-UA is free to implement more selectors than required by CSS TV.
