Thanks for the response, Steve.

iframes render the inner client width, so it treats the width of the
iframe's content as the viewport width of the inner content.

This approach would not work for @srcset, but it would work with picture
element and provide the first really good use case for it. This is because
media types with features can be used with <picture /> and I'm just talking
about a new media type.

I'm not sure if I follow your min/max content-width concern. My initial
thoughts would be that the @media content type would be an issue with
repaint and reflow for page render due to affects of text styling, similar
to issues around box model.

Did you see the example I did for this:


Thanks again!
