This patchset addresses the generic layout of the fullscreen dialogs like login
or create new account (1000,1001,1002). Graceful degradation will be addressed
using the special class selectors provided by Modernizr
(http://www.modernizr.com). Tested for IE7 - workaround for missng box-shadow
using border.

+ * Modernizr is a script that will detect native CSS3 and HTML5 features

+ * native support for it or not.
+ *
+ * In addition to that, Modernizr will add classes to the <html>
+ * element of the page, one for each cutting-edge feature. If the UA
+ * supports it, a class like "cssgradients" will be added. If not,
+ * the class name will be "no-cssgradients". This allows for simple
+ * if-conditionals in CSS styling, making it easily to have fine
+ * control over the look and feel of your website.
