242645 - *|*:root; 'overflow' property should not be applied to the viewport

Status: RESOLVED WORKSFORME

(Core :: Layout, enhancement)

Description

[Anne (:annevk)]

See also bug 230554 comment 6. Note that we currently do not apply 'overflow'
from xhtml|body to the viewport (and that is correct):
http://annevankesteren.nl/test/css/p/overflow/xhtml-body.xml

The URL works correctly in Opera 7.5p3.

Ian, this seems like your sort of thing to QA....

What is the spec likely to end up saying about this issue?

Comment 2

[Hixie (not reading bugmail)]

It's likely to say "@viewport allows..." etc.

This may end up being INVALID. Together with bug 242646. The CSS WG seems to
have changed the plan of action again.

Well if browsers implemented what the specs said in the first place, we wouldn't
have to _change the spec_ to match what was interoperably implemented. :-P

Attachment: testcase

Although this bug may be invalid. We are not setting |overflow| to the viewport
at the moment. Somehow we set the scrollbar to the viewport but make it relate
to the width of the HTML element. See the testcase for a simple example.

I meant of course, root element.

Opera actually applies 'overflow' directly to the root element. I just tested it
with the attached testcase. The CSS WG must have been testing something
different I guess. (There is no interoperable implementation here.)

This got fixed at some point.
