TEIstyle

TEIstyle is a stylesheet suite and processing toolkit designed for rendering TEI-encoded texts. It provides a consistent presentation layer across multiple output formats, including HTML, PDF, and ePub, by using TEI XML input, a set of XSLT transformations, and CSS styling rules. The aim is to reflect typographic and structural conventions found in the TEI Guidelines, supporting scholarly editions, annotations, and critical apparatus with predictable layouts.

Core components of TEIstyle typically include a collection of XSLT stylesheets that transform TEI documents into target formats, an accompanying CSS file for web presentation, and a configuration system that maps TEI elements to presentation rules. It also offers templates for front matter, headings, notes, apparatus, and bibliographic references, and supports customization through TEI ODD-based mechanisms or explicit parameter files to adjust typography, line length, heading numbering, and note placement.

Usage usually involves running an XSLT processor on a TEI document with the TEIstyle stylesheets. The workflow can produce HTML for online viewing, or integrate with formatting pipelines to generate PDFs or eBooks via FO or related technologies. TEIstyle emphasizes accessibility and interoperability, providing sensible defaults while allowing project-specific adjustments and reuse across related TEI projects.

Development and status of TEIstyle are typically community-driven within the TEI ecosystem and distributed as open-source software. It is designed to align with TEI guidelines and commonly coexists with other TEI stylesheets, accompanied by documentation and example projects to demonstrate scholarly edition workflows.
