CSS property object-view-box review

[khushalsagar]

Braw mornin' TAG!

I'm requesting a TAG review of a new CSS property : object-view-box.

object-view-box allows the author to specify a subset within an image that should draw within the content box of the target replaced element. This enables an author to create an image with a custom glow or shadow applied, with proper ink-overflow behavior like a CSS shadow would have.

• Explainer¹ (minimally containing user needs and example code): [css-images-4] Proposal to allow replaced elements to paint outside of their bounds w3c/csswg-drafts#7058
• Specification URL: https://drafts.csswg.org/css-images-4/#the-object-view-box
• Tests: [wpt folder(s), if available] : WPT.
• User research: [url to public summary/results of research]: N/A

• GitHub repo (if you prefer feedback filed there): N/A
• Primary contacts (and their relationship to the specification):

• Organization(s)/project(s) driving the specification: Google
• Key pieces of existing multi-stakeholder review or discussion of this specification: CSSWG issue
• External status/issue trackers for this specification (publicly visible, e.g. Chrome Status): Chrome status

Further details:

• I have reviewed the TAG's Web Platform Design Principles
• Relevant time constraints or deadlines: None
• The group where the work on this specification is currently being done: CSSWG
• The group where standardization of this work is intended to be done (if current group is a community group or other incubation venue): CSSWG
