Yes, you can use custom css

Changing space between steps in Steps Widget

I'd like to be able to increase the amount of space between steps in a Steps widget. I'm currently working with a vertical widget, but I would also like to be able to do this with a horizontal one. Increasing the height of the widget doesn't change the amount of space between steps. I imagine this is something that could be changed with custom CSS, but am unsure which property I'd need to edit. Has anyone done custom CSS for the Steps widget before?
