Hello there!
How are you there!
I couldn’t change color of sticky menu. Before I’ve tried customizing css. But it doesn’t work. Please help me out there.
Thank you.
Thank you.
Hi,
I am very well indeed, thanks. Hope you are doing great as well 
To change the sticky nav BG color: please go to Appearance >> Customize >> Custom CSS and JS >> Custom CSS box and copy and paste the CSS code from below:
.default-page #header.white-header.fixed-position, #header.white-header.fixed-position {
background: #f82b53;
border-bottom: 1px solid #f82b53;
}
Thank you
