The initial setup of the TEIViewer comes with default settings that should work for most documents using many standard TEI elements, particularly focused on the Core module. The examples shown are all using the standard, default settings of the tool.
The TEIViewer is easily adaptable, however. Most of the default settings can be changed via simple adjustments to the tv.css file. Functions of the control panel may be modified or created in the tv.js and tv.xsl files. For further details, see the download section of this site.
