Jekyll plugin for generating 'iframable' version website - with different layout (ie. without sidebar or menu) and different route (/iframe/). Now you are able to add <iframe/> with your website anywhere.
In your Jekyll site source root directory, create or open a _plugins directory. Paste iframe_generator.rb there.
IFrame Generator will create files and directories with /iframe/ prefix. All pages and posts will now have iframe versions. For example if you had post with route http://yourname.github.io/categories/news/2014-08-11-my-first-post your iframeable version of this post will be http://yourname.github.io/iframe/categories/news/2014-08-11-my-first-post.
