How To change submenu background color (continued)

I replied that the solution here worked and it was closed, however, I found it did not work.
Thread: kriesi.at/support/topic/how-to-change-submenu-background-color/

When I added

@media only screen and (max-width: 989px) {
#top .av-submenu-container {
background-color: #000000 !important;
}
}

it id the opposite of how I had it and made the header background color Black on small screens, but it also made the background of the Full Width Menu change to black. I switched it back by removing the code and both are Green again.
What I am trying to do is have the header background Black and the Full Width Menu background transparent, but it keeps filling the header color behind the container pre-scroll instead of the using the Main Content color.
