Picturefill – A Smart Responsive Images Approach
Picturefill is a Responsive Images approach that you can use today that mimics the proposed picture element using spans, for safety sake. Picturefill natively supports HD(Retina) image replacement. While numerous other solutions exist, picturefill has the added benefit of performance for the user in only being served one image.
Picturefill works best in browsers that support CSS3 media queries. Internet Explorer 8 and older have no support for CSS3 Media Queries, so in the examples above, IE will receive the first data-src image reference. Picturefill supports a broad range of browsers and devices, provided that you stick with the markup conventions provided.
