New article: Ruby markup and styling

Ruby is a name for small annotations that are rendered alongside base text. This is especially useful for Japanese and other East Asian content (ruby is known as furigana in Japanese). The Ruby Annotation specification provides a way to mark up ruby text, and has been adopted as an XHTML 1.1 module. Work is under way in CSS3 on mechanisms to support styling of ruby text. This article will introduce you to the basic mechanisms, and discuss the current state of the art with regards to ruby support.
