In a comment on FSOJ, Henry suggested using a special font and background for J inline code (which is in <tt> tags).
In fact the <tt> tags already select a fixed-pitch font that should be noticeably different from plain text, see the example in http://code.jsoftware.com/wiki/Fifty_Shades_of_J/Editing_Guidelines#Proofreading . As for background, we felt that overall this would make the pages look too fussy. However it may of interest that we will upgrade the wiki to the mediawiki 1.31 LTS version after it is released next month, and this will allow us two facilities: 1. You can create your own personal css. For example in our private test wiki, the following sets a light grey background color for any <tt> tag: tt { background:#ddd; } 2. We can also create our own tag for J inline code, e.g. <jcode>. This could default to <tt> but could be overridden in a personal css thus allowing <jcode> to differ from <tt>. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
