Hello, As far as I know you can't use any type of editor variables inside CSS rules, neither custom nor built-in ones. Can you give us more detains about how is the user changing between different branches? Maybe we can give some alternatives, like: - you can have different CSSs associated in the document type and the user can switch between them using the "Styles" button on the toolbar (when the branch changes) - you can use custom pseudo-classes [1]. Firstly, you must have rules in the CSS to match the pseudo classes, maybe like this: rootElement:-ext-branch1-pseudo-class image { content: url(..path1..) } rootElement:-ext-branch2-pseudo-class image { content: url(..path2..) } When the branch changes you must set the respective pseudo class. You can do that dynamically from the JAVA API [1] or by using an action with TogglePseudoClassOperation [2] or SetPseudoClassOperation [3].

Hi, I might be wrong here but I am finding that custom variables defined in preferences cannot be used in the CSS (editor variables are fine). If this is true, is there any way to use custom variables in the CSS? We have a case where a person might need to select images in different branches of a version control system and I need to change CSS display based on the branch selected.

Regards, Nathan
