I found the problem…my mistakes:
I didn’t changed the .scss reference in my .tsx file (in the web\packaged\client project)…it the .tsx was still using the RadComponents .scss reference.
and…
I didn’t update the main.scss file…it wasn’t importing my modified .scss file.
SO many things can go wrong for what I thought was such a simple thing to do…copy a working component, rename everything, tweak it and go. HA!
