Hello Melissa,
Pardon the confusion. The developer just replied back to me again and said to try this first:
.palette-primary .navbar-default .navbar-nav > li > a:hover,
.palette-primary .navbar-default .navbar-nav > li > a:focus {
background: #A0A0A0 !important;
}
You would need to add it in the Customizer in the CSS editor there. You can get to it by going through this trail of menus in the Customizer:
Advanced > Custom JS & CSS > Put the code in the Custom Theme CSS
If there’s code there already, you can put it under that code. If this code doesn’t work, then please send us your domain name.
Regards,
Arnel C.
