Progress Dynamics Web Development Guide

The default CSS files

The two CSS files that are included with the Progress Dynamics Web framework are:

rymain.css — Used for static Web pages. It defines styles for toolbars, tab folders, menu bars, and tree view menus.
ryapp.css — Used for Dynamics application objects. It is included by the UI Manager in all output sent to the Web browser. This file defines styles for WebDataObjects (client-side SDO proxies), toolbars, tab folders, browsers, viewers, and fields.

The default HTML layout page (default.htm) links to rymain.css and ryapp.css. See the "Applying your own style sheets" section for information about these links.
