Spec’d!

## Spec’d…

The `picture` spec has landed in both the WHATWG and W3C specs.

- [WHATWG 
`picture`](http://www.whatwg.org/specs/web-apps/current-work/multipage/edits.html#the-picture-element)
- [WHATWG 
`srcset`](http://www.whatwg.org/specs/web-apps/current-work/multipage/edits.html#attr-img-srcset)
- [WHATWG 
`sizes`](http://www.whatwg.org/specs/web-apps/current-work/multipage/edits.html#attr-img-sizes)
- [W3C 
`picture`](http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#the-picture-element)
- [W3C 
`srcset`](http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#attr-img-srcset)
- [W3C 
`sizes`](http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#attr-img-sizes)

Simon Pieters, 
[hero](https://twitter.com/zcorpan/status/478960023234945024), took on 
responsibility for all of the image-related bits of the WHATWG spec in 
order to make this happen. Simon included a nice, “non-normative” 
(aka “informal” also known as “readable”) [introduction to the 
new 
markup](http://www.whatwg.org/specs/web-apps/current-work/multipage/edits.html#introduction-0) 
along with all of the technical bits.

And, hey! Look who popped into the W3C HTML spec’s [list of 
editors](http://www.w3.org/html/wg/drafts/html/master/Overview.html#specification-editors)!

Not bad for a [Community 
Group](http://w3cmemes.tumblr.com/post/23122022271).

## …correct…

Mike Smith, who maintains the [W3C HTML 
Validator](http://validator.w3.org/nu/), is 
[adding](https://github.com/validator/syntax/commits/picture) `picture` 
spec support; it should land within a 
[fortnight](http://ircbot.responsiveimages.org/bot/log/respimg/2014-06-26#T79559). 
The under-development `picture` branch is up and running 
[here](http://qa-dev.w3.org:8888/), armed with [boatloatds of useful 
error 
messages](https://gist.github.com/sideshowbarker/8284404#file-messages-json) 
– go test your code!

[Can I Use](http://caniuse.com/) has begun tracking [`picture` 
support](http://caniuse.com/picture).

And Google’s new and wonderful [Web 
Fundamentals](https://developers.google.com/web/fundamentals/) guide now 
features the new markup in its [section on content 
images](https://developers.google.com/web/fundamentals/media/images/images-in-markup).

## …and in effect

Firefox Nightly has included `srcset` and `sizes` support for a few 
weeks – yesterday, John Schoenick (hero) [landed `picture` 
support](http://bugzil.la/picture), too. It’s currently disabled by 
default (behind the `dom.image.picture` flag), but that should 
[change](http://bugzil.la/picture-prefon) 
[soon](http://bugzil.la/srcset-prefon). John is still aiming for 
on-by-default support in Firefox 33 (which, [you may 
recall](https://github.com/ResponsiveImagesCG/newsletters/blob/master/RICG-newsletter-2014-06-13.md#three-browsers-by-halloween), 
ships on October 14th!).

Over on the Blink side of things, Yoav Weiss (who is *definitely* a 
hero) took `sizes` and `w` descriptors [out from behind their 
experimental flag](https://codereview.chromium.org/356833007/). Meaning 
that the features are on-by-default in 
[Canary](http://www.google.com/intl/en/chrome/browser/canary.html) 
*now*, and will almost certainly be enabled for millions of Chrome users 
when version 38 ships on September 26th.

Heros, all of you.

See you in a couple of weeks!
