I've made it look a bit like an example. gray left border, 1em left padding on title, 4em left margin on content, kept the normal white background though. I didn't use italics or bold because A: they looked bad in testing, B: all the examples I looked at italicized letters but not numbers and there is no way I know of to do that in CSS. Patches with better CSS gratefully accepted! To ssh://git.fedorahosted.org/git/publican.git c1a301f..cc28d75 HEAD -> devel
