Does editing and customizing css break things during upgrades?

(Non-technical User) #1

I am wondering if customizing css in a discourse instance will break things when I do an upgrade next time? Or specifically will the css be preserved after an upgrade?

It will be preserved. However, if you have custom JavaScript that is running that utilizes Discourse functionality, that may break (I’ve seen it happen with one other individual). CSS only changes shouldn’t cause any issues during upgrades though.
