Custom CSS error: missing closing ')'

Site URL: https://gioraschmidt.com/shop/g-model-ulsr

Hi there,

In searching these forums for how to remove social share buttons from my product pages via custom CSS I discovered an error in my current CSS - missing closing ')' 

I carefully analyzed the code and tried to fix, but to no avail.

I attach all examples.

Any help would be greatly appreciated.
Many thanks!!
