+ # If you want Rails to search in all the subdirectories under stylesheets, you should explicitly set <tt>:recursive</tt>:
+ #
+ # stylesheet_link_tag :all, :recursive => true
+ #
+ # == Caching multiple stylesheets into one
+ #
+ # You can also cache multiple stylesheets into one file, which requires less HTTP connections and can better be
+ # compressed by gzip (leading to faster transfers). Caching will only happen if config.perform_caching
+ # is set to true (which is the case by default for the Rails production environment, but not for the development
+ # environment). Examples:
+ #
+ # ==== Examples
+ # stylesheet_link_tag :all, :cache => true # when config.perform_caching is false =>
+ # <link href="/stylesheets/style1.css" media="screen" rel="stylesheet" type="text/css" />
+ # <link href="/stylesheets/styleB.css" media="screen" rel="stylesheet" type="text/css" />
+ # <link href="/stylesheets/styleX2.css" media="screen" rel="stylesheet" type="text/css" />
+ #
+ # stylesheet_link_tag :all, :cache => true # when config.perform_caching is true =>
+ # <link href="/stylesheets/all.css" media="screen" rel="stylesheet" type="text/css" />
+ #
+ # stylesheet_link_tag "shop", "cart", "checkout", :cache => "payment" # when config.perform_caching is false =>
+ # <link href="/stylesheets/shop.css" media="screen" rel="stylesheet" type="text/css" />
+ # <link href="/stylesheets/cart.css" media="screen" rel="stylesheet" type="text/css" />
+ # <link href="/stylesheets/checkout.css" media="screen" rel="stylesheet" type="text/css" />
+ #
+ # stylesheet_link_tag "shop", "cart", "checkout", :cache => "payment" # when config.perform_caching is true =>
+ # <link href="/stylesheets/payment.css" media="screen" rel="stylesheet" type="text/css" />
+ #
+ # The <tt>:recursive</tt> option is also available for caching:
+ #
+ # stylesheet_link_tag :all, :cache => true, :recursive => true
+ #
+ # To force concatenation (even in development mode) set <tt>:concat</tt> to true. This is useful if
+ # you have too many stylesheets for IE to load.
+ #
+ # stylesheet_link_tag :all, :concat => true
+ #
