Typo.css includes normal reset styles, plus some great styles designed for Chinese typography.
You'll want to simply use this gem to integrate it into your app.
Add this line to your application's Gemfile:
gem 'typo-rails', '~> 0.1.1'
And then execute:
$ bundle
Or install it yourself as:
$ gem install typo-rails
Add something like this to your application.css(.sass):
*= require typo
//= require typo
