Whiteboard for January 2012 LCWD

This page is a status whiteboard for CSS3 Images. We needed a lot of whiteboard for the Disposition of Comments.

The DoC lists important messages on www-style in the course of discussion. This page is listing the actions the WG needs to take to resolve the issues. See these minutes for the discussion and resolution of these issues.

Proposal

Defer directional images to L4 in order to address issue 37 (ltr/rtl annotations should be per-image() not per URL) and issue 41 (ltr/rtl annotations should be available via image-orientation)

Proposal A

Resolve on all of the following issues.

Proposal B

Drop object-fit and object-position.

I would advise on A, since there is only one significant issue. We have at least one implementation (Opera's; HP implements under the old names), and SVG would like these properties for mapping preserveAspectRatio into CSS. ~fantasai

The intention of the text that's being proposed to remove is to solve the use case of scaling an image to cover or be contained by a particular 2D size (which is what 'object-fit' does) but also resize the content box to match the concrete object size (which 'object-fit' otherwise cannot do). The text does this by triggering the resize behavior on when 'width' and 'height' are both auto but the appropriate min/max constraints are set. A sample use case would be a photo album where each image must be sized to fit within a 100×100 square, but you want to put a box-shadow or a border on the image, not on the square.

Proposal A

Resolve on all of the following issues, aggressively solicit reviews from dbaron, roc, kenny, bzbarsky, and alexmog, and go to CR.

Proposal B

Defer element() to CSS4 Images.

Rationale

Too many open issues and unreviewed significant changes.

NOTE: Tab has removed out-of-document element references, which were the source of some of the more significant issues.

Below is a summary of issues that should have explicit WG decisions:

Below is a list of issues that don't require WG attention; but the WG should be aware they exist and in some cases the commenters need to reply and verify that the edits are correct:
