Forum OpenACS Q&A: Re: ad_context_bar and link attributes
I'm not quite sure what you're aiming for, but if the context bar is enclosed within, say, a DIV that is styled with a class - e.g.
then you could define/control the styling for the links within the context bar by doing something like this:
border-bottom: 1px dotted #000000;
border-bottom: 1px solid #BB0000;
That way, I don't think a change to ad_context_bar is necessary (unless I'm very much mistaken!)
