for our current project, we have to use/extend the FormatAreaStyles.css to give content editors a good impression in the RTF editor on how the text will look like on the page.
I've done this before in other project, but for this implementation we have different website styles/types hosted in the same CMS instance (in fact 'old' styling and the 'new' design). The client doesn't want to show the new default font, colors etc. on the old RTF fields and visa-verse.
Any suggestion on how to achieve this in T2011 SP1?
