<h1 id=intro>
Introduction</h1>
<p>See <a data-biblio-type=normative data-link-type=biblio href=#biblio-css3-writing-modes title=CSS3-WRITING-MODES>[CSS3-WRITING-MODES]</a> <a href=http://www.w3.org/TR/css-writing-modes-3/#abstract-layout>Abstract Layout</a>
for details on how to map between logical and physical terms.
This mapping controls the interpretation of logical keywords and properties.</p>
<h2 class="heading settled" data-level=1 id=logical-controls><span class=secno>1. </span><span class=content>
Logical Directional Values: <span class=css>block-start</span>, <span class=css>block-end</span>, <span class=css>inline-start</span>, <span class=css>inline-end</span></span><a class=self-link href=#logical-controls></a></h2>
<p>Properties that accept physical directional keyword values
(<a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-position-3/#propdef-top title=top>top</a>, <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-position-3/#propdef-bottom title=bottom>bottom</a>, <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-position-3/#propdef-left title=left>left</a>, or <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-position-3/#propdef-right title=right>right</a>) are redefined
to also accept the appropriate logical directional keywords.
In such cases,
the logical values can be used in place of the corresponding physical values.
For properties that take multiple keywords, combinations of logical and
physical values are not allowed (unless otherwise specified in a future specification).</p>
<p>Properties can be either 1-dimensional or 2-dimensional.
When contextually constrained to one dimension,
the logical keywords are shortened.</p>
<h3 class="heading settled" data-level=1.1 id=caption-side><span class=secno>1.1. </span><span class=content>
Logical Values for the <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css2/tables.html#propdef-caption-side title=caption-side>caption-side</a> Property</span><a class=self-link href=#caption-side></a></h3>
<table class="definition propdef partial"><tr><th>Name:<td><a class=css data-link-type=property href=http://dev.w3.org/csswg/css2/tables.html#propdef-caption-side title=caption-side>caption-side</a><tr><th>New values:<td class=prod>block-start <a data-link-for="" data-link-type=grammar href=http://dev.w3.org/csswg/css-values-3/#comb-one title=|>|</a> block-end <a data-link-for="" data-link-type=grammar href=http://dev.w3.org/csswg/css-values-3/#comb-one title=|>|</a> inline-start <a data-link-for="" data-link-type=grammar href=http://dev.w3.org/csswg/css-values-3/#comb-one title=|>|</a> inline-end</table>
<p>The <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css2/tables.html#propdef-caption-side title=caption-side>caption-side</a> property is 1-dimensional in CSS2.1,
but was 2-dimensional in CSS2.0,

Logical Page Classifications</span><a class=self-link href=#logical-page></a></h2>
<p>In CSS, all pages are classified by user agents as either left pages
or right pages. <a data-biblio-type=normative data-link-type=biblio href=#biblio-css21 title=CSS21>[CSS21]</a> Which page is first in a spread, however,
depends on whether the page progression is left-to-right or right-to-left.</p>
<p>To allow control of page breaking to the page that is on the earlier
or later side of a spread, rather than to the left or right side of a
spread, this module introduces the following additional keywords for the
<a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css2/page.html#propdef-page-break-after title=page-break-after>page-break-after</a> and <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css2/page.html#propdef-page-break-before title=page-break-before>page-break-before</a> properties <a data-biblio-type=normative data-link-type=biblio href=#biblio-css21 title=CSS21>[CSS21]</a>:</p>
<dl data-dfn-for=logical-page data-dfn-type=value>
<dt><dfn class=css data-dfn-for=logical-page data-dfn-type=value data-export="" id=valdef-logical-page-recto>recto<a class=self-link href=#valdef-logical-page-recto></a></dfn>
<dd>
Equivalent to <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-position-3/#propdef-right title=right>right</a> in left-to-right page progressions
and <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-position-3/#propdef-left title=left>left</a> in right-to-left page progressions.
<dt><dfn class=css data-dfn-for=logical-page data-dfn-type=value data-export="" id=valdef-logical-page-verso>verso<a class=self-link href=#valdef-logical-page-verso></a></dfn>
<dd>
Equivalent to <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-position-3/#propdef-left title=left>left</a> in left-to-right page progressions
and <a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-position-3/#propdef-right title=right>right</a> in right-to-left page progressions.
</dl>
<p>These values are further defined in <a data-biblio-type=normative data-link-type=biblio href=#biblio-css3-break title=CSS3-BREAK>[CSS3-BREAK]</a>.</p>
<p>Logical page selectors are also added to support logical page selection.
Authors typically place page numbers using physical placements,
but the contents of headers often follows conventions depending
on which page in the spread is earlier.</p>
<p>Following <a href=http://www.w3.org/TR/CSS21/page.html#page-selectors>page
selectors</a> are added to support this scenario:</p>
<dl data-dfn-for=logical-page-selector data-dfn-type=value>
<dt><dfn class=css data-dfn-for=logical-page-selector data-dfn-type=value data-export="" id=valdef-logical-page-selector-recto>:recto<a class=self-link href=#valdef-logical-page-selector-recto></a></dfn>
<dd>
Equivalent to ':right' in left-to-right page progressions
and ':left' in right-to-left page progressions.
<dt><dfn class=css data-dfn-for=logical-page-selector data-dfn-type=value data-export="" id=valdef-logical-page-selector-verso>:verso<a class=self-link href=#valdef-logical-page-selector-verso></a></dfn>
<dd>
Equivalent to ':left' in left-to-right page progressions
and ':right' in right-to-left page progressions.
</dl>
<p>The logical page selectors have specificity equal to the ':left'
and ':right' page selectors.</p>

Shorthand Properties with <a class=css data-link-type=maybe href=#valdef-background-image-transform-logical title=logical>logical</a> Keyword</span><a class=self-link href=#logical-shorthand-keyword></a></h3>
<p>The shorthand properties for margin, padding, and border set values
for physical properties by default. But authors can specify the <a class=css data-link-type=maybe href=#valdef-background-image-transform-logical title=logical>logical</a>
keyword at the beginning of the property value to indicate that the values
map to the logical properties instead of the physical ones.</p>
<p class=issue id=issue-daeb2fa3><a class=self-link href=#issue-daeb2fa3></a>
other candidates of the keyword are: <span class=css>relative</span>, <span class=css>script</span>,
<span class=css>writing-mode</span>, <span class=css>beas</span>, or the value itself (e.g., <span class=css>vertical-lr-ltr</span>)
<p>The following <a data-biblio-type=normative data-link-type=biblio href=#biblio-css21 title=CSS21>[CSS21]</a> shorthand properties accept the <a class=css data-link-type=maybe href=#valdef-background-image-transform-logical title=logical>logical</a> keyword:</p>
<ul>
<li><a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css2/box.html#propdef-margin title=margin>margin</a></li>
<li><a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css2/box.html#propdef-padding title=padding>padding</a></li>

<li><a class=property data-link-type=propdesc href=http://dev.w3.org/csswg/css-backgrounds-3/#border-width title=border-width>border-width</a></li>
</ul>
<p>The syntax for these properties is effectively changed by replacing</p>
<pre><<var>value-type</var>>{1,4}</pre>
<p>with</p>
<pre>logical? <<var>value-type</var>>{1,4}</pre>
<p>When the logical keyword is present in the value, the values that follow are
assigned to the logical properties as follows:</p>
<ul>
<li>If only one value is set, the value applies to all four logical sides.</li>
<li>If two values are set, the first is for block-start and block-end,
the second is for inline-start and inline-end.</li>
<li>If three values are set, the first is for block-start,
the second is for inline-start and inline-end,
and the third is for block-end.</li>
<li>If four values are set, they apply to the block-start, inline-end, block-end, and inline-start
sides in that order.</li>
</ul>
<p class=issue id=issue-5ae45c09><a class=self-link href=#issue-5ae45c09></a>
Should the shorthand also reset the physical properties to their initial
values?
<div class=example>
In the following example, the two rules are equivalent:
<pre><code>
blockquote {
margin: logical 1em 2em 3em 4em;
}
blockquote {
margin-block-start: 1em;
margin-inline-end: 2em;
margin-block-end: 3em;
margin-inline-start: 4em;
}
</code></pre>

<h3 class="no-ref heading settled" id=conventions><span class=content>
Document conventions</span><a class=self-link href=#conventions></a></h3>
<p>Conformance requirements are expressed with a combination 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 the normative parts of this
document are to be interpreted as described in RFC 2119.
However, for readability, these words do not appear in all uppercase
letters in this specification.
<p>All of the text of this specification is normative except sections
explicitly marked as non-normative, examples, and notes. <a data-biblio-type=normative data-link-type=biblio href=#biblio-rfc2119 title=RFC2119>[RFC2119]</a></p>
<p>Examples in this specification are introduced with the words "for example"
or are set apart from the normative text with <code>class="example"</code>,
like this:
<div class=example>
<p>This is an example of an informative example.</p>
</div>
<p>Informative notes begin with the word "Note" and are set apart from the
normative text with <code>class="note"</code>, like this:
<p class=note>Note, this is an informative note.</p>
<p>Advisements are normative sections styled to evoke special attention and are
set apart from other normative text with <code><strong class="advisement"></code>, like
this:
<strong class=advisement>
UAs MUST provide an accessible alternative.

<h3 class="no-ref heading settled" id=conformance-classes><span class=content>
Conformance classes</span><a class=self-link href=#conformance-classes></a></h3>
<p>Conformance to this specification
is defined for three conformance classes:
<dl>
<dt>style sheet
<dd>A <a href=http://www.w3.org/TR/CSS21/conform.html#style-sheet>CSS
style sheet</a>.
<dt>renderer
<dd>A <a href=http://www.w3.org/TR/CSS21/conform.html#user-agent>UA</a>
that interprets the semantics of a style sheet and renders
documents that use them.
<dt>authoring tool
<dd>A <a href=http://www.w3.org/TR/CSS21/conform.html#user-agent>UA</a>
that writes a style sheet.
</dl>
<p>A style sheet is conformant to this specification
if all of its statements that use syntax defined in this module are valid
according to the generic CSS grammar and the individual grammars of each
feature defined in this module.
<p>A renderer is conformant to this specification
if, in addition to interpreting the style sheet as defined by the
appropriate specifications, it supports all the features defined
by this specification by parsing them correctly
and rendering the document accordingly. However, the inability of a
UA to correctly render a document due to limitations of the device
does not make the UA non-conformant. (For example, a UA is not
required to render color on a monochrome monitor.)
<p>An authoring tool is conformant to this specification
if it writes style sheets that are syntactically correct according to the
generic CSS grammar and the individual grammars of each feature in
this module, and meet all other conformance requirements of style sheets
as described in this module.
<h3 class="no-ref heading settled" id=partial><span class=content>
Partial implementations</span><a class=self-link href=#partial></a></h3>
<p>So that authors can exploit the forward-compatible parsing rules to
assign fallback values, CSS renderers <strong>must</strong>
treat as invalid (and <a href=http://www.w3.org/TR/CSS21/conform.html#ignore>ignore
as appropriate</a>) any at-rules, properties, property values, keywords,
and other syntactic constructs for which they have no usable level of
support. In particular, user agents <strong>must not</strong> selectively
ignore unsupported component values and honor supported values in a single
multi-value property declaration: if any value is considered invalid
(as unsupported values must be), CSS requires that the entire declaration
be ignored.</p>
<h3 class="no-ref heading settled" id=experimental><span class=content>
Experimental implementations</span><a class=self-link href=#experimental></a></h3>
<p>To avoid clashes with future CSS features, the CSS2.1 specification
reserves a <a href=http://www.w3.org/TR/CSS21/syndata.html#vendor-keywords>prefixed
syntax</a> for proprietary and experimental extensions to CSS.
<p>Prior to a specification reaching the Candidate Recommendation stage
in the W3C process, all implementations of a CSS feature are considered
experimental. The CSS Working Group recommends that implementations
use a vendor-prefixed syntax for such features, including those in
W3C Working Drafts. This avoids incompatibilities with future changes
in the draft.
</p>
<h3 class="no-ref heading settled" id=testing><span class=content>
Non-experimental implementations</span><a class=self-link href=#testing></a></h3>
<p>Once a specification reaches the Candidate Recommendation stage,
non-experimental implementations are possible, and implementors should
release an unprefixed implementation of any CR-level feature they
can demonstrate to be correctly implemented according to spec.
<p>To establish and maintain the interoperability of CSS across
implementations, the CSS Working Group requests that non-experimental
CSS renderers submit an implementation report (and, if necessary, the
testcases used for that implementation report) to the W3C before
releasing an unprefixed implementation of any CSS features. Testcases
submitted to W3C are subject to review and correction by the CSS
Working Group.
<p>Further information on submitting testcases and implementation reports
can be found from on the CSS Working Group’s website at
<a href=http://www.w3.org/Style/CSS/Test/>http://www.w3.org/Style/CSS/Test/</a>.
