<h2 class="no-num no-toc" id="abstract">Abstract</h2>
<p><em>This is the first draft of the CSS3 Hyperlink Presentation Module. It
is published to get some early feedback. The properties in it and even the
scope of the draft are still very unstable. The draft may be dropped or
merged with another.</em>
<p>CSS (Cascading Style Sheets) is a simple language for describing the
presentation of documents. This specification is a module of level 3 of CSS
and contains the functionality required to describe the presentation of
hyperlink source anchors and the effects of hyperlink activation.

<h2 id="dependencies"><span class="secno">1. </span>Dependencies</h2>
<p>This CSS3 module depends on the following other CSS specification(s):
<ul>
<li><cite>CSS2.1</cite> <a href="#CSS21" rel="biblioentry">[CSS21]</a>
<!-- <li><cite>CSS3 module: syntax</cite> <a href="#CSS3SYN" rel="biblioentry">[CSS3SYN]</a></li>
<li><cite>CSS3 module: values and units</cite> <a href="#CSS3VAL" rel="biblioentry">[CSS3VAL]</a></li>
<li>[etc]</li> -->
</ul>
<p>It has non-normative (informative) references to the following other CSS3
modules:
<ul>
<li><cite>Selectors</cite>[[SELECTORS]]
<li><cite>CSS3 Basic User Interface Module</cite><a href="#CSS3UI"
rel="biblioentry">[CSS3UI]</a>
<li><cite>CSS3 Generated and Replaced Content Module</cite> <a
href="#CSS3GENCON" rel="biblioentry">[CSS3GENCON]</a>
</ul>
<h2 id="requirements"><span class="secno">2. </span>Requirements and
principles</h2>
<p>A hyperlink is a combination of a link with the semantic of an external
reference, something which is considered outside the content document. This
is in contrast to an embed, which is a link with the semantic of an internal
reference, something which is considered a part of the document (such as an
embedded image). There are also local hyperlinks which simply point to
navigation points (anchors) in the current document.
<p>A hyperlink is a combination of a link with a certain behavior: it is a
link that is presented in such a way that the user recognizes it as something
he can activate quickly and easily (with a mouse click, key press, etc.), and
which, on activation causes the <em>target reference</em> of the link to be
retrieved and displayed to the user, shortly after activation.
<p>The scope of this CSS module can be summarized with the following list of
principles:
<ol>
<li>Linking semantics and link presentation are separable <a
href="#TAGLINK20030116" rel="biblioentry">[TAGLINK20030116]</a>. The task of
CSS is presentation.
<li>The aspects of a hyperlink that differ depending on device, platform or
user accessibilty <a href="#WCAG" rel="biblioentry">[WCAG]</a> requirements
are likely to be presentational <a href="#TAGLINK20030116"
rel="biblioentry">[TAGLINK20030116]</a>.
<li>The presentation of a document should normally be specified separately
from its content, and preferably in a CSS style sheet.
<li>Some parts of behavior are presentational; e.g., CSS can say that
activation of a hyperlink causes a new window to pop up (but not, e.g., that
the activation sends a POST request to a server). The specifiable behaviors
include:
<ul>
<li>replace current document or portion of a document by target
<li>pop up a temporary window (possibly modal) with the target
<li>ditto, but pop "under"
<li>show target in a specific window
<li>using tabs in a tabbed interface rather than windows in the above
</ul>
<li>CSS is also able to suppress all behavior, thus making it impossible to
activate a hyperlink. UAs should always allow the user to disable particular
style sheets.
<li>CSS can be used to describe a large class of common hyperlink styles, but
not all possible styles.
<li>CSS doesn't rely on specific mark-up in a source document, but is able to
style hyperlinks in many different document formats. In particular, it can
style HTML <a href="#HTML401" rel="biblioentry">[HTML401]</a> and XHTML <a
href="#XHTML10" rel="biblioentry">[XHTML10]</a> documents, documents that use
HLink <a href="#HLINK" rel="biblioentry">[HLINK]</a>, a large part of XML <a
href="#XML10" rel="biblioentry">[XML10]</a> documents that use XLink <a
href="#XLINK10" rel="biblioentry">[XLINK10]</a>, e.g. SVG <a href="#SVG10"
rel="biblioentry">[SVG10]</a> and several others.
<li>The boundary between semantics and style is not sharp. For ease of use,
CSS sometimes has to allow some aspects of semantics to be expressed in CSS.
E.g., CSS style rules may say which attribute of an element that has several
is used for the hyperlink. (But CSS is not able to say, e.g., what base to
use to resolve relative URLs <a href="#RFC1808"
rel="biblioentry">[RFC1808]</a>.)
<li>The previous point notwithstanding, CSS assumes that, in general, the UA
has knowledge about the document format from other sources (or hardcoded) and
classifies elements as hyperlinks or not. E.g., the CSS pseudo-classes
':link' and ':visited' match only elements that are hyperlinks.
</ol>
<p>This module does <em>not</em> deal with
<ol>
<li>Replaced elements, i.e. embeds.
<li>Footnotes.
<li>Event bindings.
</ol>
<p>Even though replaced elements are represented in many mark-up languages in
ways that are syntactically similar to hyperlinks (often an element with an
attribute that holds a URI <a href="#URI" rel="biblioentry">[URI]</a>
reference), in terms of both semantics, and typically presentation, they are
different. Replaced elements are defined in the CSS3 Content module <a
href="#CSS3GENCON" rel="biblioentry">[CSS3GENCON]</a>.
<p>Footnotes often serve similar purposes as hyperlinks, but in
non-interactive documents. <!--
Footnotes are handled in the ??? module [ref].
No formal proposal or draft as of yet.
Informal proposal by Ian Hickson here:
http://lists.w3.org/Archives/Member/w3c-css-wg/2002JulSep/0299.html
-->
<p>Activation of a hyperlink needs an action (event) by the user, e.g., a key
press or a mouse click. This module does not define what events activate
which links. Some such UI issues (not only for hyperlinks) are dealt with in
the CSS3 Basic UI module <a href="#CSS3UI" rel="biblioentry">[CSS3UI]</a>.
<h3 id="open-issues"><span class="secno">2.1. </span>Open Issues</h3>
<p class="issue">The following open issues have been recognized, and are
documented here for the purpose of discussion. All issues MUST be resolved
before CR.
<ul>
<li class="issue">How are secondary (or even tertiary) links styled? Do they
need to be? Or should their interactivity be left up to the user agent?
</ul>
<h2 id="target0"><span class="secno">3. </span>Target properties</h2>
<p>These properties specify where the target of a <!-- primary --> hyperlink
is displayed, after activation of the hyperlink. Not all UAs support all
values. <!--

<p>Both 'target-position' and 'target-new' only apply if due to the value of
'target-name', a new tab (or window) is being created. Neither
'target-position' nor 'target-new' can actually <em>cause</em> a new

<p>The 'target' property is a shorthand property for setting the individual
target properties (i.e., 'target-name', 'target-new' and 'target-position')
at the same place in the style sheet.
<p> Given a valid declaration, the 'target' property first sets all the
individual target properties to their initial values, then assigns explicit
values given in the declaration.
