           Cascading Style Sheets (CSS) Requirements for RFCs

Abstract

   The HTML format for RFCs assigns style guidance to a Cascading Style
   Sheet (CSS) specifically defined for the RFC Series.  The embedded,
   default CSS as included by the RFC Editor is expected to take into
   account accessibility needs and to be built along a responsive design
   model.  This document describes the requirements for the default CSS
   used by the RFC Editor.  The class names are based on the classes
   defined in "HTML for RFCs" (RFC 7992).
