I want to completely re-style our osTicket system to match our company, so that means back-end and what the client sees. Is it possible to just re-code the entire css according to the design? and if so when we upgrade/update how do we keep the styling?Any help would be greatly appreciated :)
Yes, you can edit the css files and any files in the project.You do not. Upgrading will break your customizations.That being said, version 2.0 (which is a very long way off) is supposed to have a themeable UI.
