We are building a website that has multiple themes that can be applied to it, based on user selection.
The page content type is made up of Paragraphs (from the paragraph module), each of which can have a background image via an Image field.
Sometimes it is necessary to have these background images vary by theme. Is there an existing way to allow a different image to be added to a node per theme? Obviously this can be achieved through each theme's CSS, but it would be great to expose the functionality to the site editor rather than making it a development task.
