Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v3.2.13) is shown here.

These similar methods exist in v4.1.8:

stylesheet_link_tag(*sources) public

Returns a stylesheet link tag for the sources specified as arguments. If you don’t specify an extension, .css will be appended automatically. You can modify the link attributes by passing a hash as the last argument. For historical reasons, the ‘media’ attribute will always be present and defaults to “screen”, so you must explicitely set it to “all” for the stylesheet(s) to apply to all media types.

Examples

stylesheet_link_tag "style" # =>
  <link href="/stylesheets/style.css" media="screen" rel="stylesheet" type="text/css" />

stylesheet_link_tag "style.css" # =>
  <link href="/stylesheets/style.css" media="screen" rel="stylesheet" type="text/css" />

stylesheet_link_tag "http://www.example.com/style.css" # =>
  <link href="http://www.example.com/style.css" media="screen" rel="stylesheet" type="text/css" />

stylesheet_link_tag "style", :media => "all" # =>
  <link href="/stylesheets/style.css" media="all" rel="stylesheet" type="text/css" />

stylesheet_link_tag "style", :media => "print" # =>
  <link href="/stylesheets/style.css" media="print" rel="stylesheet" type="text/css" />

stylesheet_link_tag "random.styles", "/css/stylish" # =>
  <link href="/stylesheets/random.styles" media="screen" rel="stylesheet" type="text/css" />
  <link href="/css/stylish.css" media="screen" rel="stylesheet" type="text/css" />

You can also include all styles in the stylesheets directory using :all as the source:

stylesheet_link_tag :all # =>
  <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" />

If you want Rails to search in all the subdirectories under stylesheets, you should explicitly set :recursive:

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 :recursive option is also available for caching:

stylesheet_link_tag :all, :cache => true, :recursive => true

To force concatenation (even in development mode) set :concat to true. This is useful if you have too many stylesheets for IE to load.

stylesheet_link_tag :all, :concat => true
