Extended CSS Style for Quick selection

I was trying to change the font and color of quick selection menus and Items using the "Extended CSS Style". It works on quick selection for Retail mode. But in Hospitality mode, it is not working. Font and color stay the same. Even if it's possible to have multi lines in the buttons or decrease the margins or padding. I tried it but it has no affect on Quick selection in Hospitality mode.

Can some one help with that?
