I know that we can change design elements in Harmony and Quick Grid by means of user classes, but I'm wondering how practical it would be to add some custom CSS to alter the built-in themes. Would this be more trouble than it's worth?
What would be great is if I could redefine the colours in one place, and have the redefinitions effect both plugins.
Again, perhaps user classes do that already...but it would be great if there was a way to alter say, all the beige themed items in my site at once.
Any good way to go about this?
