##Claudio's CSS Background-Image lab
This is just a single page application - a quick hack, really - to be able to easily play with the background-image CSS property on some predefined container dimensions (think about them as the templates for the most common used mobile device resolution).
JavaScript and CSS are self-contained inside the single index.html and there is an external dependency for jQuery.
The settings are automatically saved in localStorage across sessions (you need to be using a fairly recent browser, of course).
