Some of our users are asking for a dark version of our theme, I’ve been resisting because I know what a nightmare it is having to maintain two separate themes (particularly when they are as customised as ours).
Having the option of child-themes would make life a lot easier. Essentially, child themes work by inheriting from a parent theme and ONLY changes made in the child theme take effect when that theme is chosen.
This means that after creating the initial theme, you go on to create a child theme (say make the background colour and posts darker with CSS overrides) then, if you ever make any changes to the parent theme in future, those changes automatically carry through to the child unless they are specifically overridden. (We don’t have templates on DC but the same principle would apply to templates too - the parent theme templates are used unless a modified version in the child has been created.)
Do you have any plans to add something like this? If not, is it something you would consider please?
