Hi, I'm not an expert, but I think the trick is in using rgba colors <http://www.css3.info/preview/rgba/>:
tiddler-background: rgba(0,0,0,0.25); The first three numbers code for the color, and the last number (0.25) is the opacity (only for the background color, and not for the children of the elements, as I understand it). -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
