CSS and RichText in Notes Client

I think I’m very close to getting this to work, but I’m not quite there. I have a form with a rich-text field on it. I would like to apply a CSS style to just the RT field to override whatever styles a user might have used (mostly this is copy/paste from different sources in different formats and we want to achieve consistency in formatting).

I have tried creating a stylesheet and setting FontSize: 12px Font-Family: Ariel to BODY and this works, but it applies the style across the whole document.

So I created a custom .BODYTEXT class with that setting and I added BODYTEXT to the RT field’s HTML class field. This does nothing.

I tried adding pass-thru-html css code inline with my RT field in a DIV tag. This does nothing.

Can someone clue me in on what I’m missing? Thanks.
