CSS Autoprefixer OMG!!!

Posting on Rails channel, since there is a [gem](https://github.com/ai/autoprefixer-rails) for using [this amazing tool](https://css-tricks.com/autoprefixer/) with your Rails apps. Using Autoprefixer, you no longer have to worry about writing or maintaining vendor-specific CSS properties. (The ones with the dash prefixes.) You just use the latest W3C standards, and the rest is taken care of for you with post-processing.
