I am trying to load a CSS framework, Blueprint, onto my Rails 3.1 application.
In Rails 3.0+, I would have something like this in my views/layouts/application.html.e
Even though Rails 3.1 (RC) allows use of SASS files-- it doesn't force it.
Files in your /public/stylesheets will still be served just fine.
If you wish to activate the SASS parser (and utilize the new framework), rename your my_styles.css to be my_styles.css.scss and put it in the /app/assets/stylesheets folder. Then include just your application.css in your application.erb.html after uncommenting out the require_self / require_tree lines in it.
For more info, here is a blog i pulled up after a quick google search: http://www.rubyinside.com/how-to-rails-3-1-coffeescript-howto-4695.html
As for the IE 8 thing. There was a bug in IE not not always executing conditions, so try
its a bit of hackery to try and reset the parser to execute the rule
