Chapter 10. Style Sheets

Table of Contents
10.1. CSS

XML is concerned with content, and says nothing about how that content should be presented to the reader or rendered on paper. Multiple style sheet languages have been developed to describe visual layout, including Extensible Stylesheet Language Transformation (XSLT), Document Style Semantics and Specification Language (DSSSL), and Cascading Style Sheets (CSS).

The FDP documents use XSLT stylesheets to transform DocBook into XHTML, and then CSS formatting is applied to the XHTML pages. Printable output is currently rendered with legacy DSSSL stylesheets, but this will probably change in the future.

10.1. CSS

Cascading Style Sheets (CSS) are a mechanism for attaching style information (font, weight, size, color, and so forth) to elements in an XHTML document without abusing XHTML to do so.

10.1.1. The DocBook Documents

The FreeBSD XSLT and DSSSL stylesheets refer to docbook.css, which is expected to be present in the same directory as the XHTML files. The project-wide CSS file is copied from doc/share/misc/docbook.css when documents are converted to XHTML, and is installed automatically.
