How can I add a custom color to my main menu bar?

Hi folks,

I have a sticky main menu on my store. But the background for this menu is transparent so it does not look good while scrolling the web page. How can I add a custom color to the main menu bar?

My store is vollmart24.com

Add this code

nav.main-menu {
  background-color: #ff0000;
}
