Plugins - Cascading Stylesheets
Add to favoritesCascading Stylesheets is a plugin that enhances the behaviour of the built-in stylesheet_link_tag macro to support a :defaults parameter. If :defaults is passed as a parameter, the stylesheet_link_tag macro will load the following stylesheets (if present) in order:
- application.css;
- #{RAILS_ENV}.css (ie development.css, production.css, uat.css, etc.); and
- #{controller_name/action_name}.css (eg. home/index.css, customers/new.css, etc.).
This allows you to define application-wide, environment-specific (such as different backgrounds for UAT and production) and page-specific styles without needing to manually link each one.
To use, simply call stylesheet_link_tag from application.rhtml (in much the same way as you would use javascript_include_tag) passing :defaults as a (or the only) parameter:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
...
<%= stylesheet_link_tag :defaults %>
<%= javascript_include_tag :defaults %>
...
