I just pasted the code above (.main-navigation) into a Simple CSS, saw that there wasn’t a result and didn’t save it.
It would be awesome if you add something in GP!)
Anywahy, thanks or helping!)
P.S. if you will have any information how to do it or something else, please, write!) I’m here and will see your message.
P.P.S. if you have few minutes, you can log in my site and paste this code into Simple CSS (Customize) and see a result 🙂
