Hi WebApps Working Group.
The CSS WG discussed the "pre-LCWD" version of your View Modes Media
Feature spec [1] during our weekly conf call yesterday.
The raw minutes of the call are available [2]. In summary:
1. globally positive feedback about the spec; we agree the feature
is needed.
2. this should not be restricted to widgets; we suggest to expand
the scope of the document.
3. about values:
- is the 'all' value really useful since a (view-mode: all) query
is always true?
- a rendering can be 'application' and 'fullscreen'; isn't there
an orthogonality issue here? Same thing for 'application' and
'maximized' for instance
- chrome can be added by the windows manager or by the application
itself, does it make a difference?
- is a 'hidden' value needed to query whether a window is visible?
- if the current medium (CSS-speaking) is 'projection', does it
assume view-mode is fullscreen? What about the other way round?
(Opera for instance assumes 'projection' when fullscreen is on)
- Is it possible to be floating but also have a media type
'projection'?
- the background of the viewport is often applied through CSS, and
that could lead to circular dependencies because the media query
would depend on the result of the cascade
- more generally, we think some of the value definitions could
be clearer, it can be hard to understand if a given rendering
matches a value or not.
4. all these queries could/should have an event-based counterpart so the
changes are detectable by code. We understand this is outside of the
scope of this spec but that's still an important comment.
