I don’t know about you, but it often occurs to me afterwards that I could put certain CSS settings into a class. If these are simple, like just padding, it’s not a thing. But as soon as gradients, shadows and fonts etc… it gets complicated.
I am not aware of any such feature or workaround where you can select certain settings and then packet them into your class. Now you have to delete everything and restore the class with all settings, right?
