Breadcrumbs not picking up settings file configuration

Hi

I am using FM11, RH10 as part of TCS 4.0.

I am creating a settings file that will be used by team to generate WebHelp outputs. In this, I want to change the default Times New Roman font of breadcrumbs to Arial. While I am aware how to set that during publishing, I don't want to take that approach because I don't want my team to fiddle around too many things during the publishing process.

In the RHStyleMapping.css file I used to create the ISF, I saw the breadcrumbs option and changed it to Arial. However, that did not help.

Is it possible to achieve what I am trying to achieve? If yes, please advise me how.

Thanks.
