在Rails 3.1中加载print.css

Question

如何在Rails 3.1中加载print.css文件？

Answer 1

不确定是否需要适用于打印介质的打印css

以下内容应达到目的 - stylesheet_link_tag“print”，：media =＆gt; “打印”

Answer 2

实际上，如果您查看application.css文档，您会看到：

/*
* This is a manifest file that'll automatically include all the stylesheets available in this directory
* and any sub-directories. 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 . 
*/

这意味着将包含application.css（require_self）以及stylesheets文件夹中的其他CSS（require_tree。）。

我是Rails的初学者，所以我无法进一步解释！ 搜索有关require_self，require_tree和SASS语言的任何信息。
