Nice to find this piece of info but:
why its not configurable after a year of this post?
why i cant see whole code you sent in any of these browsers, edge, chrome, ffox? hitting F12 and looking into site code helping here…
Stepe - sorry for late response but do you still need a hand here?
Here is the code form the code snippet, i guess part of it is covered by the vertical line, we will fix it soon,
Let me know if this code worked or if you need anything else
#site-navigation{
background-color: #ff0000;
}
.menu li a{
color: #ff0000;
}
