Hey Dane!
I’m not sure where “#menu-header-menu” is, so I’m assuming I just replaced it like you said.
This is what my style.css looks like for the child theme:

.navbar .nav.navbar-nav ul ul {
top: 0;
left: 100%;
padding: 0;
margin: 0;
}
so I’m assuming you just copy and paste the .navbar code he gave us. Sorry if it’s unclear, I’m not super experienced with these things.
