From XOWA: the free, open-source, offline wiki application
XOWA wiki pages are styled with CSS.
Overview
XOWA stores the CSS for a wiki page in the following directory: C:\xowa_release\user\anonymous\wiki\ For example, for simple.wikipedia.org, the css is in C:\xowa_release\user\anonymous\wiki\simple.wikipedia.org
The logo in the upper right-hand corner is called logo.png and stored in C:\xowa_release\user\anonymous\wiki\simple.wikipedia.org\html\logo.png
The CSS files are downloaded automatically from Wikimedia servers. xowa_common.css is the main file. xowa_wiki.css is the contents of the css at simple.wikipedia.org/wiki/MediaWiki:Commons.css
