1 Dense is a jQuery plugin that offers an easy way to serve device pixel ratio aware images, bringing in retina support to your website.
2 The plugin should work decently well with Zepto on the most up to date WebKit browsers, but doesn't contain any specific compatibility code for it.
3 The image tag doesn't define data- x attribute, so we are defaulting to src .
