The community members are discussing how to copy the style guide from a hosted app to a self-hosted one. The initial suggestion is to use copy-paste, but the community members note that the global root variables don't seem to be copied. They suggest copying the global root variables, and selecting them in the CSS preview, copying, and inserting them in the advanced panel when adding styles. The community members also discuss the difference between the CSS preview and the advanced panel, noting that the CSS preview is for output while the advanced panel is for input, and that the CSS preview panel is likely going away as the advanced panel is being improved.
