I have tried now a thousand times, but I don't get it to work ... especially concerning not only the background color, but also concerning the "+" and "-" icons.
I would like to have the toggler with
- white background, when it is in the sidebar as a widget (this is okay with the CSS that come with CORONA)
- grey background (my own new toggle background color), when it is
a) a footer widget
b) within a normal post
Could you please tell me how to solve this?
