jquery.mobile

参考：http://d.hatena.ne.jp/arcright/20120905/1346755680

1.公式サイトからzipをダウンロードして回答
http://jquerymobile.com/download/
Zip File: jquery.mobile-1.2.0.zip (JavaScript, CSS, and images)

2.ファイルを配置

$ mkdir app/assets/images/images
$ mkdir app/assets/images/images/jquery.mobile 
$ mkdir app/assets/stylesheets/jquery.mobile
$ cp ~/Downloads/jquery.mobile-1.2.0/images/* app/assets/images/images/jquery.mobile/
$ cp ~/Downloads/jquery.mobile-1.2.0/*.css app/assets/stylesheets/jquery.mobile/
$ rm app/assets/stylesheets/jquery.mobile/*min.css

3.cssのimageのパスを修正

$ vim app/assets/stylesheets/jquery.mobile/jquery.mobile.theme-1.2.0.css
%s/images/\/assets\/images\/jquery.mobile/g 

4.application.cssを編集

$ vim app/assets/stylesheets/application.css

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new file per style scope.

 *= require_self
 *= require_tree .
