Hi www-style, When an image or a video has "object-fit" and/or "object-position" set, it would be quite convenient for web developers if they had a way to determine the exact on-screen rect that the media is rendering into. We (Mozilla) received a request for such a feature here: https://bugzilla.mozilla.org/show_bug.cgi?id=1211711 https://bugzilla.mozilla.org/show_bug.cgi?id=1211717 Briefly, the use case is a web author wanting to know where a user's cursor is, relative to a <video>'s rendered content. 3 QUESTIONS: ========== (1) Is this positioning information already easily-exposed somewhere? (I don't think it is, but I might've missed it.) (2) What should an API to query this information look like? Maybe a new getter "DOMRect getConcreteObjectRect()" on all replaced elements? (This may really be a question for the WHATWG -- not sure -- but since object-fit & object-position are defined in CSS, I figured I'd start with the CSSWG.) (3) Any reasons we shouldn't expose an API like this? Thanks, ~DanielReceived on Wednesday, 7 October 2015 04:18:47 UTC
