The available style sheets to select as default for a profile or for your users to select are based on special entries in the web.config.
Here is the list of CSS files as distributed--you may want to remove style sheets for protocols that you do not have running in your installation.
<!-- one per each Stylesheet you want to give options for, css1, css2, css3 and so on, must be unique-->
<add key="css1" value="SCStyle.css;Standard;"/>
<add key="css2" value="SCStyle5251.css;Greenscreen;"/>
<add key="css3" value="SC3270.css;Color 3270-Traditional;"/>
<add key="css4" value="SC3270Clr.css;Color 3270-Input Backlit;"/>
<add key="css5" value="SCColor.css;Color 5250-Input Backlit;"/>
<add key="css6" value="SC5250Clr.css;Color 5250-Traditional;"/>
<add key="css7" value="SCStyleVT.css;VT100/220/320/ANSI;"/>
<add key="css8" value="SCStyleFP.css;FlipPC Gray;" />
<add key="css9" value="SCStyFPBlk.css;FlipPC Black" />
Note that the key must start with "css" followed by a number to make the key unique--also, the file name of the CSS file is followed by a semicolon and the description that users see in the Settings.
If you only have a 3270 host, you can edit the above list so that it looks like:
<!-- one per each Stylesheet you want to give options for, css1, css2, css3 and so on, must be unique-->
<add key="css1" value="SCStyle.css;Standard;"/>
<add key="css2" value="SC3270.css;Color 3270-Traditional;"/>
<add key="css3" value="SC3270Clr.css;Color 3270-Input Backlit;"/>
The "Standard" css file is one that attempts to make the screen look more like a typical web page rather than the "dark mode" terminal emulator.
