Hi Saguaros,
It is actually the other way around, Guru is using the classes of the UIkit framework (https://getuikit.com/).
That framework was developed by the popular template designer Yootheme, and it was used in all their templates for many years.
All the CSS classes in that framework start with the prefix "uk-", and the problem is that by Guru using those classes in its code, it is affecting the deisgn of every template that uses the framework.
A solution would be that Guru changes the prefix to other string, for example "gr-", so that the CSS hardcoded in Guru does not affect the templates developed by Yootheme:

Could this please be implemented?
Best,
Roger.
