Expanding on Is background-position-x (background-position-y) a standard W3C CSS property? -- is there a polyfill for CSS background-position-x/y?
I found https://github.com/liuxuanzy/jquery-backgroundfix but I'm having some trouble making it work:
- Pure JS: http://jsbin.com/ripegiqose/1/edit
- Ruby on Rails (Bower + http://rails-assets.org/): http://runnable.com/VL0J_279Y69u6gxa/rails-jquery-backgroundfix
