Issue: Add final level 3 content
30+
This module describes CSS properties which enable authors
31+
to style user interface related properties and values.
32+
33+
<a href="http://www.w3.org/TR/REC-CSS1#anchor-pseudo-classes">Section 2.1 of CSS1</a> [[CSS1]]
34+
and <a href="http://www.w3.org/TR/CSS2/ui.html">Chapter 18 of CSS2</a> [[CSS2]]
35+
introduced several user interface related properties and values.
36+
<a href="http://www.w3.org/TR/2000/WD-css3-userint-20000216">User Interface for CSS3 (16 February 2000)</a> introduced several new user interface related features.
37+
38+
[[CSS3-UI]] was later introduced to incorporates, extends, and supersedes these.
39+
This specification continues this work, and in turn replaces [[CSS3-UI]].
40+
41+
Note: At the time of writing, [[CSS3-UI]] is not completely finalized yet.
42+
To avoid accidental divergences and maintenance overhead,
43+
This specification is written as a delta specification over CSS-UI Level 3.
44+
Once the level 3 specification is final,
45+
its content will be integrated into this specification,
46+
which will then replace it.
47+
Until then, CSS-UI Level 4 only contains additions and extensions to level 3.
48+
49+
<h3 id="purpose">Purpose</h3>
50+
51+
The purpose of this specification is to achieve the following objectives:
52+
<ul>
53+
<li>Extend the user interface features in CSS2.1 and [[CSS3-UI]]
54+
<li>Provide additional CSS mechanisms to augment or replace other
55+
dynamic presentation related features in HTML.
56+
<li>Introduce directional navigation properties to assist in the construction of
57+
user interfaces which make use of a directional navigation model.

for editors of specifications to informatively answer.

970+
Per the <a href="https://w3ctag.github.io/security-questionnaire/#questions">Questions to Consider</a>
971+
972+
<ol>
973+
<li>Does this specification deal with personally-identifiable information?
974+
<p>No.</p>
975+
</li>
976+
977+
<li>Does this specification deal with high-value data?
978+
<p>No.</p>
979+
</li>
980+
981+
<li>Does this specification introduce new state for an origin that persists across browsing sessions?
982+
<p>No.</p>
983+
</li>
984+
985+
<li>Does this specification expose persistent, cross-origin state to the web?
986+
<p>No.</p>
987+
</li>
988+
989+
<li>Does this specification expose any other data to an origin that it doesn’t currently have access to?
990+
<p>No.</p>
991+
</li>
992+
993+
<li>Does this specification enable new script execution/loading mechanisms?
994+
<p>No.</p>
995+
</li>
996+
997+
<li>Does this specification allow an origin access to a user’s location?
998+
<p>No.</p>
999+
</li>
1000+
1001+
<li>Does this specification allow an origin access to sensors on a user’s device?
1002+
<p>Yes. The directional focus navigation properties indirectly allow access to the device's keyboard navigation input mechanism such as arrow keys.</p>
1003+
</li>
1004+
1005+
<li>Does this specification allow an origin access to aspects of a user’s local computing environment?
1006+
<p>No.</p>
1007+
</li>
1008+
1009+
<li>Does this specification allow an origin access to other devices?
1010+
<p>No.</p>
1011+
</li>
1012+
1013+
<li>Does this specification allow an origin some measure of control over a user agent’s native UI?
1014+
<p>Yes. The 'cursor' and 'caret-*' properties enable the page to change the display of the cursor and text insertion caret of the user agent’s native UI. In addition the 'outline-style' property’s ''outline-style/auto'' value (and thus 'outline' shorthand) enable the page to potentially display a native focused element outline presentation around any element.</p>
1015+
<p>The 'appearance' property also allows author to turn off native styling and replace it with css based styling.
1016+
</li>
1017+
1018+
<li>Does this specification expose temporary identifiers to the web?
1019+
<p>No.</p>
1020+
</li>
1021+
1022+
<li>Does this specification distinguish between behavior in first-party and third-party contexts?
1023+
<p>No.</p>
1024+
</li>
1025+
1026+
<li>How should this specification work in the context of a user agent’s "incognito" mode?
1027+
<p>No differently.</p>
1028+
</li>
1029+
1030+
<li>Does this specification persist data to a user’s local device?
1031+
<p>No.</p>
1032+
</li>
1033+
1034+
<li>Does this specification have a "Security Considerations" and "Privacy Considerations" section?
1035+
<p>Yes.</p>
1036+
</li>
1037+
1038+
<li>Does this specification allow downgrading default security characteristics?
1039+
<p>No.</p>
