Good day, just bought the accordion extension as i would like to run your tabs extension inside the accordion. However, after installing the accordion extension, i do not have a .css file (other than an empty one) and i seem to not be able to find any ways to modify. what am I missing?

I found that the black-tie (in my case) is the default for all possibilities as this is what i used for my tabs.
one last question:
Accordion: Can I make the headers the same background color, both active and default.
