changing AdminLTE css without editing generated css files

Hi,
My project is in Persian (RTL). I need to change transform value of .ribbon-wrapper .ribbon to -45 degree.
May I do that without editing generated css file? Can I do that directly in PHPMaker?

please suggest sample code.

Google for the related css code.

You may put that css code from “HTML” → “Styles” → “User”, after that re-generate the project css file, and then make sure you have already done a hard refresh/reload from your browser to make sure you have already used the latest version of your project css file.
