I object to this proposal. I think it is inappropriate for HTML to require things about the styling in general. Document conformance requirements in HTML do not and should not...

I wonder if the feature should more explicitly check for the case of no dimensions being specified, since the behavior is a bit weird in that case. - When no...

> So, how to fix this? Use 100vw if the computed value (not used value) of the 'width' and 'min-width' properties are both `auto`? Done in fc651c8993932014a8ab67cd27e2087ebff9a37e. I suppose since...

To answer my own question, I think we have these: - ['inline-size' and 'block-size'](https://drafts.csswg.org/css-logical-1/#dimension-properties); which is the width depends on 'writing-mode' - sizing values ([css-sizing-3](https://drafts.csswg.org/css-sizing-3/#sizing-values) and [css-sizing-4](https://drafts.csswg.org/css-sizing-4/#sizing-values)) can also be...

Maybe a more general approach would be: An element's **concrete object size ignoring natural dimensions** is its [concrete object size](https://drafts.csswg.org/css-images-3/#concrete-object-size) but acting as if there are no [natural dimensions](https://drafts.csswg.org/css-images-3/#natural-dimensions), thus...

I went with the approach described in the comment above. I believe it solves the problem discussed in https://github.com/whatwg/html/pull/8008#issuecomment-1176203523 and, at least in spec terms, doesn't introduce a lot of...

(Need to rebase this after https://github.com/whatwg/html/pull/8175 is merged.)

@yoavweiss PTAL :)

I'm a bit worried about compat for making more things "relevant mutations". Should we gate the new additions on usage of `w` descriptors in `srcset`?
