Css file for default Xojo web theme

I’m aware that I can import a whole new theme from Bootswatch or elsewhere which will over-ride the default Xojo web theme, but I want to start from the existing theme and modify it only slightly.

Where can I find a copy of the css file that Xojo uses? I’d like to modify it and re-import, leaving most of the standard theme unchanged.
