jquery mobile data-theme not working

Question

I have a simple log in page and I\'m trying to apply theme \"b\" to it, but it doesn\'t work. The page looks dark and not the way theme b should look like. Any idea?

Answer 1

Update

The classic theme should be upgraded to work properly with jQuery Mobile 1.4.x

Unlike old versions of jQuery Mobile, the latest version 1.4 has only two themes/swatches a and b. The latter is dark/black theme.

1. You can either create your own themes using ThemeRoller.

2. Use classic style sheet offered by jQuery Mobile, along with default style sheet.
