Srcset

Code (pretend the [ and ] are the appropriate angly bits):

[img alt="@srcset experiments"
	src="srcset_base.gif"
	srcset="srcset_2x.gif 2x,
		srcset_768w.gif 768w,
		srcset_768w_2x.gif 768w 2x,
		srcset_1024w.gif 1024w,
		srcset_1024w_2x.gif 1024w 2x"
	style="display:block;margin:1em auto;border:2px solid #000;"]

Alternate code, verify browser attributes:

• http://www.webkit.org/demos/srcset/
• http://atmedia.info
• Plain version of this page.

Added Sept-19-2013:

• This page offered by Coast as one that works, but it uses a polyfill: http://eightmedia.github.io/yass.js/demo/
• I copied that page and dropped the YASS.js and Modernizr script (since I don't know how to make Coast surf with JS disabled), and it doesn't work in Coast: /files/Prototype/YASS-JS_noJS.html
• Now if I add YASS.JS and Modernizr to my page (with no other changes), the srcset works: /files/Prototype/srcset_YASS.html
