 === Combinations
 
 At times, it is useful to combine multiple stylesheets and serve them as one resource.  For example you may have two sets of stylesheets: one for traditional web views and one for mobile web views.  Rails' provides the :cache option on 'stylesheet_link_tag' helper to provide this function, ie:
 
     stylesheet_link_tag 'reset', 'common', 'app_web', :cache => 'web'
