Thanks for the quick reply.
Well, the modifications are small (mainly change in colors and fonts) but have to be applied to many classes. And the UI/UX guy who will make it is not familiar with NodeBB but is familiar with Bootstrap.
With this context in mind, do you still advice doing the changes as Custom CSS (I guess you mean using the option in the Admin panel) ?
Sorry, if my question may sound stupid but I have a short experience with NodeBB and mainly with the API part...
Turn off Skin in Persona Theme
How to turn off user choose skin in Persona Theme?
You can hide the option via custom CSS. I'd like to remove it eventually for good, although lots of people still use skins
@paopevil Go to ACP -> Settings -> User and enable the option "Prevent users from choosing a custom skin".
@pichalite Thank you! This working!
