936481 - Implement `src-n` attribute on img element

Status: RESOLVED WONTFIX

(Core :: DOM: Core & HTML, defect)

Description

[Marcos Caceres [:marcosc]]

The RespImg Syntax [1] introduces a new "src-n" attribute set on the img element that accepts a small set of microsyntaxes. These microsyntaxes address the viewport-based selection, device-pixel-ratio-based selection, and art direction use cases described in this document. The proposal claims to avoid the implementer concerns associated with the `picture` element proposal and supersedes the `srcset` syntax.

[Henri Sivonen (:hsivonen)]

Why unconfirm this?

Comment 2

[Tim Nguyen :ntim]

This spec was deprecated. It's back to srcset.

Comment 3

[John Schoenick [:johns]]

Current target is implementing srcset and picture

Comment 4

[David Bruant]

Taking the liberty to re-add dev-doc-needed. Firefox and other implementors deciding to implement some solutions and not others to solve the "responsive image" problem is worth documenting. The information of the why-s is scattered over implementors and standards mailing-lists, but it'd be good to have a documentation summarizing all that.
Feel free to remove it again if you disagree or think this belongs somewhere else (like in its own doc bug)
