Hi, I am new to context, migrating from latex for the purpose of writing an online book. I would like to set up a few definitions in the environment file that would replace latex's \begin{definition} ... \end{definition} environments. I realize that this can be done conveniently with \defineenumeration, but I want of course a few more features in it then in latex's setup. For example, I'd like to have the definition typeset in some color against some background. I tried the following in the environment file: \setupcolors[state=start] \definetextbackground [defbackground] [backgroundcolor=blue, backgroundoffset=.25cm, offset=.25cm, frame=off, location=paragraph, color=green] \defineenumeration [definition] [text=Definition, location=left, before={\starttextbackground[defbackground]}, after={\stoptextbackground}, letter=it] Then, in the text, when I use \startdefinition This is my definition. \stopdefinition the text comes out green all right, but the blue background is smeared all over two pages. I have tried a few modifications to no avail, so I fear I am doing it all wrong. Curiously, when I typeset the above th first time, I only get the green text (no blue), and the mess shows only up when typesetting the second time. Any help? Thanks, Matthias
