Hello,

1-
Jean-Yves, why the dev-doc-needed keyword if the pseudo-classes have not been implemented yet?

2-
The appropriate layout component for this bug should be Printing: Output

3-
This bug should be blocking bug 605520 and it does not block bug 115199

4-
There is a bunch of tests on :left, :right, :first pseudo-classes at

http://test.csswg.org/suites/css2.1/latest/html4/chapter-13.htm#s13.2.2
and also at
http://test.csswg.org/suites/css2.1/latest/html4/chapter-13.htm#s13.2.1
and
http://test.csswg.org/suites/css2.1/latest/html4/chapter-13.htm#s13.2

5- 
I propose to update the summary to read:

Support for @page :left, :right, :first selectors (pseudo-classes)

so that this helps finding this bug report when searching

6-
css2 and testcase keywords should be added

7- 
OS field should be All

Re: 1. 

Gerard, dev-doc-needed will allow this bug to appear on our list of tasks once RESOLVED. There is no need to read every comment on it until it is RESOLVED to be sure to add ddn at the right moment.

A question about the change to the Summary:  

Have all the other selectors in @Page been implemented?  If not, in which bug report is that deficiency described?

Comment 5

[Gérard Talbot]

Hello David,

As far as CSS 2.1 is involved, there are only 3 selectors for @page at rule. 

CSS Paged Media Module Level 3 
http://www.w3.org/TR/css3-page/#page-selectors
also lists :blank. 

Specialized/customized at-rules like {@top-left-corner, @top-left, @top-center, @top-right, @top-right-corner, ..., @bottom-right-corner} are different issues and should probably be filed in another bug report when/once CSS Paged Media Module Level 3 reaches Candidate Recommendation.

:jwatt, could you consider increasing the bug severity?

The last needinfo from me was triggered in error by recent activity on the bug. I'm clearing the needinfo since this is a very old bug and I don't know if it's still relevant.

[Emilio Cobos Álvarez [:emilio]]

We do support this, is it only bug 1869211 which causes it to be considered not supported? I wouldn't consider it a major bug...

Comment 10

[James Graham [:jgraham]]

Per the web-features definition it's css.selectors.left and css.selectors.right that are marked as unsupported. If those things are actually supported it may just be that we need to update the BCD data.

Comment 11

[Emilio Cobos Álvarez [:emilio]]

Pretty sure we do support them, Emily can you confirm just in case?

Comment 12

[Emily McDonough [:alaskanemily]]

We can parse all of these, but we do nothing with anything but :first.
So no, we don't support left/right yet.
