Looking to get confirmation on whether or not nested CSS is supported in prince, I'm pretty sure the answer is not currently, however posting this for two reasons. An official confirmation and for historical record to help other end users. Thank you all!

Nested CSS is not supported in Prince yet, no.

Thank you for the confirmation!

+1 for this feature. I recently dug into this and I think it would greatly improve the maintainability of my code. I started using it for web development and absolutely like it.

Yes, we'd love to see this too!
