## What it is
Han.css (漢字標準格式) is a Sass/Stylus and JavaScript typography framework that provides print-quality, standardized typesetting for Hanzi-based web pages. It supports Traditional Chinese, Simplified Chinese, and Japanese with features like punctuation compression, ruby annotations, emphasis marks, and Hanzi-Latin inter-character spacing.

## Use cases
- style Chinese web pages with print-quality typography
- add ruby furigana annotations to Japanese or Chinese text
- fix CJK punctuation rendering and compression on the web
- mix Chinese and Latin text with proper spacing
- render vertical text layouts in the browser
- normalize default styles for hanzi reading habits

## When to choose
- building a website or article page primarily in Chinese or Japanese
- you need advanced CJK typographic features like punctuation squeezing, hanging punctuation, or emphasis dots
- you want semantic HTML5 styling without presentational classes

## When to avoid
- your content is primarily Latin-script and only occasionally includes CJK characters
- you need a general-purpose CSS framework for layout or UI components
- you require guaranteed long-term updates, as the project has seen infrequent releases
