Пакет: libjs-img.srcset (2.0.0~20131003~dfsg-2.1)

fast JavaScript polyfill for img srcset

img.srcset is a lightweight, no nonsense, all browser supporting, fast polyfill for img srcset, allowing for lighter yet backwards-compatible responsive web design.

The srcset attribute is an HTML extension for adaptive (a.k.a. responsive) images. More info at <http://www.w3.org/TR/html-srcset/>.

A polyfill is (in the context of HTML5) Javascript code implementation of a functionality often available in modern web browsers, allowing web designers to use simpler standards-compliant and declarative code, burdening only older/simpler browsers with these fallback snippets.
