Edit carousel navigation control

hi guys, how can i give a background color to the carousel navigation arrows? i can change the arrow color using the sub class nav icon, but i don’t understand how to give the background color to the arrow.
see image to look what I’d like to do

You can do so directly from the class manager.

yes, but in that way I can change the stroke color. as you can see in the image I posted, I’d like to put a background color to those arrows.

This has been discussed on the forum many times. Typing ‘carousel’ in the search box will help you. A while ago I posted a solution to add custom icons.
