CSS code for Custom HTML modules

Is there a way to write custom CSS from the new drag & drop design editor? We are seeing issues when forwarding emails.

Hi did not see it yesterday when i checked it out for the first time. But you could create your own custom module in the Design Manager and use it in the new Email Drag and Drop Editor. (you have to click on the “more” button in the bottom right corner).
