Hi team, 
We want to stylize a window “Does this article answer your question?” and the ticket form background “Description”. 

As you can see from the screenshots above, we have customized other elements to be dark, but these windows are not customizable, as they are most likely hardcoded. We searched for these elements and tried different variations with the available code of the default Copenhagen theme, but unfortunately, nothing worked.
Zendesk Support confirmed that these elements are hardcoded. We know that it is possible to upload your own theme, but that still requires more resources, and we only need to style these elements.
Please advise if it is possible to make these elements customizable? Thank you.
